摘　　要：目的:研究显现、提取现场潜在指印的新光源及其应用。方法:设计并研制"法庭科学物证检验LED面光源",利用该光源以定向反射法显现、提取遗留在玻璃、皮革等10种物体表面的潜在指印。结果:成功研制出"法庭科学物证检验LED面光源",利用该光源以定向反射法显现、提取遗留在玻璃、皮革等10种物体表面的潜在指印,有效显现率达90%。结论:法庭科学物证检验LED面光源为现场勘查提供了一种新光源,该光源可以有效显现、提取遗留在玻璃、皮革等多种物体表面的潜在指印。Objective： Design a new light source and study it＇s applications in revealing latent fingerprint. Methods： Develop the LED surface light source for forensic science examination, use the light source to revealing latent fingerprint on 10 kinds of material surface by the method of directional reflection illumination. Results： The LED surface light source has been successfully used in revealing latent fingerprint on glass, leather and other surface, 90% of the fingerprint appeared. Conclusion： The LED surface light source for forensic science examination is provided as a new light source, The light source can effectively revealing the latent fingerprint on glass, leather and other surface.
