Comparative Study on Sweat Fingerprints Photographic Effects between Full-Band CCD and UV Observing Photograph Systems

Abstract:

Using the full-band CCD (PL4240 UV, FLI) and Yunnan Zhihai ultraviolet observation camera system (UVYNZH-II) shoot sweat fingerprints on A4 wrapper and A4 printing paper, to comparatively analyze the effects these two camera systems. The clarity and contrast of ultraviolet image captured from Full-band CCD is better than from UV observation camera system, but both devices are able to reflect the fingerprint ridge characteristics. For sweat fingerprints, it is better for the full-band CCD, but under good conditions for sweat fingerprints bridges, UV observation camera system can basically meet the requirements of sweat fingerprint UV shooting.
