一种新型物证摄影技术的探索

低温荧光摄影是用摄影方法记录物证在低温状态下被激发出荧光图像的一种技术，同普通荧光摄影一样，它是利用光致发光原理来显现隐性痕迹物证，但又克服了普通荧光摄影中被拍物荧光亮度低、物证细节特征无法再现等缺陷，增加了物证的反差，而且对检材不造成任何损坏，是物证摄影中非常有效的一种技术手段．着重阐述了低温荧光摄影的方法、类型，以及在物证检验中的运用，

A Modern Explore About Material Evidence Photography

Cryofluography is a technology by using photographic method to record the fluoroshadowgraph of material evidence excited in the low temperature. As the common flourography, it takes the advantage of photoluminescence to show. The implicit material evidence but overcome it's shortcomings including fluoro-briliance of being photoraphied materials is too dull, particular features of material evidence can not reappear, etc. also it not only can increase the contrast of material evidence, but doesn't have any destruction to materials which are to be examined. It is a very efficient technical medium in material evidence examination. The methods types and application of cryofluography in material evidence examination were expounded mainly.
