摘　　要：本文从理论上论述了多功能痕迹物证摄影仪的基本结构和使用方法。利用现有的近距摄影装置、球形摄影仪、彩色偏光镜和偏振摄影灯等设备，对常见痕迹物证进行模拟拍摄实验证明是可行的。解决了拍摄光滑金属物体表面遣留痕迹时的反光干扰问题和加强反差摄影时光照角度不能连续可调的问题。In this paper,the basic structure and application method of multi-functional photograph-ic equipment of trace mark evidence was discussed theoretically.It was proved that simulated test of photograph of common trace mark evidence using existing equipment of short distance photograph,ball-shaped photographic equipment monochromatic polariscope and polarizating light photographic lamp was practicable. And it resolved problems which disturb of reflected light was produced during shooting residuary trace evidence on smooth surface of metal objects and the angle of light could be adjusted con-tinuosly during strengthening contrast photo.
