摘　　要：目的　探索汗潜指纹显现的新方法。方法　利用低温荧光摄影方法加强指纹沉积物的固有荧光强度 ,来提高汗潜指纹显现的成功率。结果　在 4 1 5nm波段激发下用黄滤色镜拍摄指纹的显现效果最好。Objective To set up a new method for developing latent fingerprint. Method Low temperature fluorescence technique was used. Result Under 415nm wave band light, and using yellow filter lens, we get the best developing of fingerprint. Conclusion Low temperature fluorescence photography is the efficient technology to develop latent fingerprint.
