| 摘 要： | 目的研究镜面客体上潜在指印的偏振光照相显现方法。方法用偏振光照相分别对普通镜面和CD盘上的油脂指纹、灰尘指印进行显现。结果显现指纹清晰,通过与定向反射、暗视场照相方法进行比较,偏振光照相效果明显好于其他光学方法。结论偏振光照相可以有效地增加指印纹线与背景的亮度反差,消除物体背景干扰。

| Abstract: | Objective To explore a method to develop latent fingerprint on mirrory surface.Method Polarization photography was used to develop latent fingerprint on mirrory surface.Result To compare with the directional reflection photography and darkfield photography,polarization photography is better than the other methods.Conclusion Polarization photography can effectively increases the contrast and eliminates interference function of the object background. |
