在照明与数字分析层面，系统内置可分区控制LED照明光源，鉴定人可根据痕迹的三维形态灵活选择不同角度和区域的组合照明方案——侧光可凸显线条痕迹的隆起与凹陷，低角度掠射光可增强浅表擦划痕迹的阴影对比，多分区组合可实现无影立体照明效果。搭载的高清晰彩色数字摄像头实时采集显微图像与视频，配套的专业测量与分析软件支持图像采集、存储、处理、二维与三维尺寸精确测量（如长度、角度、半径、深度差等）、特征标注及比对分析。全部测量数据可导出并直接生成标准格式检验报告，检验过程与结果完全符合工具痕迹同一认定技术规范对图像记录与数据量化的专业要求。工作台为XY手动检测台，尺寸333mm×360mm，移动范围203mm×203mm，可容纳大型、不规则或批量检材。

核心功能与合规实战价值

镜头360°电动旋转全景观察，实现环形与曲面痕迹的无死角连续检验

系统核心创新功能为镜头在水平面内360°电动连续旋转。在枪弹痕迹检验中，鉴定人只需将弹头固定于载物台，通过电动控制使镜头绕弹头圆周旋转，即可连续、完整地观察整圈膛线痕迹的走向、间距及起止点特征，无需手动反复转动弹头。在圆柱形工具表面擦划痕迹或锁芯内壁刮擦痕迹的检验中，360°旋转功能可使鉴定人从任意水平角度连续观察痕迹在曲面上的分布规律。该全景检验能力从根本上解决了传统显微镜固定视角下环形和曲面痕迹必须分段观察、手动拼接图像导致特征关联性断裂的检验难题，使痕迹的全圆周特征分析从断续片段升级为连续整体，极大提升了痕迹形态学分析的全面性与鉴定结论的科学可靠性。

35X-243X连续变倍与分区控制LED照明，覆盖从宏观寻迹到微观线条接合比对的全流程需求

系统物镜支持0.7X至4.5X连续变倍，总放大倍率覆盖35X至243X。鉴定人在低倍率下快速搜索定位大范围的痕迹区域，在发现可疑特征后直接无级放大至高倍率进行微观线条的接合比对，全程无需更换物镜。内置可分区控制LED光源支持多种组合照明方案，可根据痕迹的立体形态灵活切换，最佳化凸显痕迹的阴影、层次与纹理细节。该宽范围连续变倍与多模式照明组合使单一设备即可覆盖从宏观痕迹分布搜索到微观线条特征比对的全部检验环节，满足工具痕迹同一认定技术规范对检验放大倍率与照明条件的全面要求。

专业测量软件与数据量化输出，推动工具痕迹鉴定从定性形态描述走向定量数据分析

配套的专业测量与分析软件支持对显微图像进行二维与三维尺寸精确测量——包括线条宽度、间距、角度、半径及深度差等关键比对参数——所有测量数据均以数字形式保存，支持导出并直接生成标准格式检验报告。该数据量化能力使工具痕迹的鉴定结论从依赖鉴定人经验判断的定性形态描述，转变为具有精确数值支撑的客观数据分析，鉴定文书所附的测量数据与比对图像可在法庭质证中为鉴定意见提供经得起科学验证的技术证据支撑。

Product Overview

The SW-1 3D Video Microscopic Examination System — 360° Horizontal Motorized Rotation, 0.7X-4.5X Continuous Zoom, 35X-243X HD Stereoscopic Imaging, Precision Motorized Control & Digital Measurement Comparison Platform (also referred to as the SW-1 3D Video Microscope or 3D Motorized Video Microscope) is an advanced microscopic examination device integrating high-precision three-dimensional observation, motorized control, and digital analysis into a single unit. It constitutes a core digital microscopic comparison platform in the fields of criminal technical tool mark examination, firearm trace examination, and 3D evidence identification. This product is deeply customized for the in-depth examination and fine comparison of three-dimensional evidence such as tool marks and firearm traces in the field of judicial forensic identification. It perfectly adapts to various professional scenarios, including the 3D feature analysis of the bottom and walls of shear marks, the assessment of the starting/ending points and striation direction of prying marks, the complete circumferential observation of rifling traces on bullets, the 3D morphological comparison of firing pin impressions and ejector marks on cartridge cases, the identification of the three-dimensional embossed edges and ink accumulation of stamp impressions, and the comprehensive examination of multiple types of 3D trace evidence such as fiber cross-sections, metal fracture surfaces, and bone injury morphology. The system enables 360° horizontal motorized rotation observation of the lens head, combined with a 0.7X to 4.5X continuous zoom objective lens and a total magnification range of 35X to 243X. It is further complemented by a 333mm × 360mm large-format precision moving stage and professional measurement and analysis software. This fundamentally resolves the operational pain points that have long plagued tool mark examination work, such as the inability of traditional stereomicroscopes with fixed viewing angles to perform blind-spot-free observation of circular and curved surface traces, the low positioning efficiency and risk of missing features caused by repeatedly moving evidence manually, and the difficulty in quantitatively documenting and comparatively analyzing three-dimensional traces. It provides trace evidence examiners with "a motorized 360° panoramic viewing angle, continuous zoom from macro to micro, zone-controlled illumination for highlighting three-dimensionality, and precision measurement for data quantification" professional-grade 3D trace digital examination and comparison capability. It is a critical core piece of criminal technical equipment that drives the development of specialized identification work, such as tool mark examination, towards automation, precision, and digitization.

Technical Principle

This system operates on a synergistic architecture of three technologies: optical stereoscopic imaging, precision motorized mechanical transmission, and digital image analysis. At the optical imaging level, the system is equipped with a 0.7X to 4.5X continuous zoom objective lens. Combined with the eyepiece and built-in optical magnification system, it achieves a total magnification range of 35X to 243X. The examiner can quickly search and locate a large area of the trace at low magnification, and then steplessly zoom in to the target magnification for high-magnification fine observation of the microscopic striation features on the bottom and walls of the trace, without needing to change the objective lens or interrupt the observation throughout the entire process.

At the motorized mechanical transmission level, the core innovation of the system lies in the 360° horizontal motorized rotation function of the lens head. The fixed viewing angle of traditional stereomicroscopes forces the examiner, when observing circular traces (such as bullet rifling) or curved surface traces (such as scratch marks on cylindrical tool surfaces), to manually and repeatedly rotate the evidence to intermittently observe the feature distribution across the entire circumference. The lens head of this system can perform 360° motorized continuous rotation in the horizontal plane. The examiner only needs to fix the evidence on the stage and, through motorized control, rotate the lens head around the evidence. This allows for the continuous and complete observation of the trace's orientation, undulating morphology, and starting/ending point features from any horizontal angle, without the need to manually move the evidence. This motorized rotation mechanism also supports fine angle adjustment and uniform speed scanning, ensuring that the target remains clearly focused throughout the rotation.

At the illumination and digital analysis level, the system features a built-in zone-controlled LED illumination light source. The examiner can flexibly select combined illumination schemes from different angles and zones based on the three-dimensional morphology of the trace—side lighting can highlight the ridges and depressions of striation marks, low-angle grazing light can enhance the shadow contrast of superficial scratch marks, and multi-zone combinations can achieve a shadowless stereoscopic illumination effect. The onboard high-definition color digital camera captures microscopic images and videos in real time. The accompanying professional measurement and analysis software supports image capture, storage, processing, precise 2D and 3D dimensional measurement (such as length, angle, radius, depth difference, etc.), feature annotation, and comparative analysis. All measurement data can be exported and used to directly generate examination reports in a standard format. The examination process and results fully comply with the professional requirements for image documentation and data quantification stipulated in the technical standards for tool mark identification. The stage is an X-Y manual inspection stage with dimensions of 333mm × 360mm and a travel range of 203mm × 203mm, capable of accommodating large, irregular, or batch evidence samples.

Core Functions and Compliance Operational Value

360° Motorized Rotational Panoramic Observation of the Lens Head, Enabling Blind-Spot-Free Continuous Examination of Circular and Curved Surface Traces

The system's core innovative function is the 360° motorized continuous rotation of the lens head in the horizontal plane. In firearm trace examination, the examiner only needs to fix the bullet on the stage. By motorized control, the lens head rotates around the circumference of the bullet, allowing for the continuous and complete observation of the orientation, spacing, and starting/ending point features of the entire circumference of rifling traces, without the need to manually and repeatedly rotate the bullet. In the examination of scratch marks on the surfaces of cylindrical tools or the inner walls of lock cylinders, the 360° rotation function enables the examiner to continuously observe the distribution pattern of the traces on the curved surface from any horizontal angle. This panoramic examination capability fundamentally resolves the examination challenge posed by traditional microscopes with fixed viewing angles, where circular and curved surface traces must be observed in segments and images manually stitched, leading to a fragmentation of feature correlation. It upgrades the analysis of a trace's full-circumference features from discontinuous fragments to a continuous whole, greatly enhancing the comprehensiveness of trace morphological analysis and the scientific reliability of the identification conclusion.

35X-243X Continuous Zoom and Zone-Controlled LED Illumination, Covering the Full-Process Needs from Macroscopic Trace Searching to Microscopic Striation Matching Comparison

The system's objective lens supports continuous zoom from 0.7X to 4.5X, with the total magnification range covering 35X to 243X. The examiner can quickly search and locate a large area of the trace at low magnification. Upon discovering a suspicious feature, they can directly zoom in steplessly to high magnification for microscopic striation matching comparison, without needing to change the objective lens at any point. The built-in zone-controlled LED light source supports multiple combined illumination schemes, which can be flexibly switched according to the three-dimensional morphology of the trace to optimally highlight the shadow, layering, and textural details of the trace. This combination of a wide range of continuous zoom and multi-mode illumination allows a single device to cover all examination steps, from macroscopic trace distribution searching to microscopic striation feature comparison, meeting the comprehensive requirements for examination magnification and illumination conditions stipulated in the technical standards for tool mark identification.

Professional Measurement Software and Quantified Data Output, Driving Tool Mark Identification from Qualitative Morphological Description to Quantitative Data Analysis

The accompanying professional measurement and analysis software supports precise 2D and 3D dimensional measurements on microscopic images—including key comparison parameters such as striation width, spacing, angle, radius, and depth difference. All measurement data is saved in digital format, supports export, and can be used to directly generate examination reports in a standard format. This data quantification capability transforms the expert conclusion in tool mark identification from a qualitative morphological description reliant on the examiner's experiential judgment into an objective data analysis supported by precise numerical values. The measurement data and comparison images attached to the expert report can provide scientifically verifiable technical evidence support for the expert opinion during court cross-examination.

Compliant Application Scenarios

In-Depth 3D Feature Examination and Identification Scenario for Shear and Prying Marks

In tool mark examination, the examiner fixes the shear fracture surface or prying mark evidence collected from the scene onto the stage. Utilizing the 360° rotation function, the processing feature lines, undulating morphology, and starting/ending points on the bottom and walls of the mark are continuously observed from multiple horizontal angles. After locating the feature area at low magnification, the examiner zooms in to high magnification and performs a line-by-line matching comparison with test samples produced using the suspected tool. The zone-controlled illumination combination optimally enhances the stereoscopic contrast of the striations. The measurement software precisely quantifies the spacing and angles of key striations, and all comparison images and measurement data are incorporated into the forensic case file.

Multi-Angle 3D Morphological Analysis of Firearm Traces and Firearm Identification Scenario

In firearm trace examination, the examiner uses this system to perform a complete 360° circumferential observation of the rifling traces on a bullet. Simultaneously, the 3D traces on the cartridge case, such as the firing pin impression, breech face marks, and ejector marks, are morphologically compared and analyzed for their spatial distribution from different angles. This provides comprehensive three-dimensional data support for identifying or excluding the firearm from which they were discharged.

Identification Scenario for the 3D Features of Stamp Impressions and Printed Matter

In document examination, the examiner utilizes multi-angle illumination and motorized rotation observation to clearly visualize the three-dimensional embossed edges of stamp impressions, the state of ink accumulation, and the microscopic morphology of printing dots. This effectively allows for the determination of the sequence of stamping, whether it is a spliced forgery, or if it was made by the same stamp.

Core Technical Parameters

In terms of the optical system, it is equipped with a 0.7X to 4.5X continuous zoom objective lens, with a total magnification of 35X to 243X. For the observation system, the lens head supports 360° horizontal motorized rotation, allowing observation from any horizontal angle without the need to manually move the evidence. For the illumination system, a built-in zone-controlled LED illumination light source supports multiple combined illumination schemes. For image capture, an onboard high-definition color digital camera captures high-definition microscopic images and videos in real time. For the stage, it is an X-Y manual inspection stage with dimensions of 333mm × 360mm and a travel range of 203mm × 203mm. For the software system, it is equipped with professional measurement and image processing software, supporting image capture, storage, precise 2D and 3D dimensional measurement, feature annotation, and comparative analysis, with data exportable for generating examination reports.

Compliant Field Application Cases

The trace evidence examination laboratory of a municipal criminal technical science research institute accepted a tool mark identification case for a series of cable thefts. It was necessary to perform an identification comparison between multiple sections of sheared copper core cable ends collected from the scene and a bolt cutter seized from the suspect. The examiner fixed the cable ends onto the stage of the SW-1 3D Video Microscopic Examination System. At low magnification, the shear striation areas on the fracture surfaces were quickly located. The view was then continuously zoomed in to high magnification. The side-lighting mode of the zone-controlled LED light source was used to highlight the three-dimensional undulation of the striations. The examiner used the 360° motorized rotation function to continuously observe the orientation and distribution of the striations on the cylindrical copper core surface from different horizontal angles. After confirming the characteristic areas, a line-by-line matching comparison was performed with test samples made using the bolt cutter. The system's measurement software precisely measured the spacing and angles of the key striations. All comparison images and measurement data were incorporated into the forensic case file. Based on a comprehensive comparison, the examiner determined that the scene cables had been cut by that specific bolt cutter. The identification conclusion was lawfully admitted during court cross-examination.
