Abstract: The study situation of latent fingerprints development and enhancement by photoluminescence is reviewed; its principles, approaches and practical applications are summarized; and its progress trend is predicted. The development sensitivity of latent fingerprints can be enhanced by photoluminescence, resulting in a good contrast between fingerprints and substrate.

Key words: photoluminescence, latent fingerprint, development, enhancement

摘要： 本文结合本课题组的研究内容,对光致发光显现和增强潜指纹的研究状况进行了综述,重点阐述了光致发光技术的原理、方法和实际运用情况,并对将来的发展趋势进行了展望。该技术提高了潜指纹的显现灵敏度,其显出的指纹清晰、与背景之间的反差好。
