摘　　要：为了克服采用常规方法拍摄现场灰尘足迹中存在的受地板背景和其他灰尘的影响较大的问题,笔者阐述了配光检验方法与偏振光摄影方法,采用掠入射摄影加偏振光摄影的方法,得到了明显优于单纯掠入射配光摄影的灰尘足迹拍摄效果,可以达到司法鉴定的要求。In this paper, in order to overcome the existing problem influenced by floor background and other dust in shooting dust footprint of crime scene by using conventional methods, the authors expounded the methods of light distribution inspection and polarized light photography. By using grazing incidence photography plus polarized light photography method, the authors obtained shooting effect of dust footprint is obviously better than that of pure grazing incidence light distribution photography, which could meet the requirements of judicial identification.
