| 摘 要： | 本文主要论述了直接利用电子闪光灯为光源，产生垂直反射偏振光的原理、方法及在刑事摄影中的应用。通过理论研究和试验，设计出了电子闪光灯光路变换系统，解决了直接利用电子闪光灯为光源的拍摄案件现场某些光滑非金属物体时，物体表面产生强烈反射光线或反射光带和对人犯摄影、物证摄影时的强烈阴影干扰，以及无法直接用以电子闪光灯为光源，对遗留在案件现场上的痕迹进行垂直反射摄影的困难。

| Abstract: | The paper mainly discusses the principle and method of using electronic flash lamp as the only source to generate vertical reflect polarized light in the criminal photography,By theoritical study and testing,optical-path transform eyrtem of an electronic flasher is designed to solve problems that when electronic flasher is directly used to photo some smooth non-metal subjects on the site of case,re-flecting beam of the surface will be so strong as to disturb strongly the photograph of offender and evi-dence and it is impossible to use electronic flasher directly as an optical source to photo the trace leaving over on the site of case by perpendicular reflecting light. |
