Experiments on Sweat Fingerprints Reflection Effects on Different Thickness Glass Surfaces by Shortwave Ultraviolet
Original Abstract
Abstract
Objective To observe refl ection effects of sweat fi ngerprints on surfaces of glasses of different thicknesses by shortwave Ultraviolet. Method Sweat fi ngerprints on slide and cover slide were appeared by use of UV refl ectance imaging methods. The obtained results were compared. Result Differences in the thickness of the transparent glass objects signifi cantly affect the UV refl ectance imaging method for sweat fi ngerprints shooting. Conclusion For UV through the thin transparent glass, the transmission depth affects the fi ngerprints imaging. Certain methods have been proposed to improve the image quality.
