초록

Infrared imaging is known to be the most frequently used method for producing potential fingerprints. However, if the background of the fingerprint absorbs infrared light, it is difficult to read the existing fingerprint. This study used an infrared - polarized effect to suppress infrared absorption in the background so that only fingerprints could stand out. For this purpose, an optimal method of infrared - polarized imaging is proposed. Images taken at 0, 45, 90, and 135 degrees are made into DOLP images through Stokes Q, Stokes U, and analyzed. As a result, the structure and form analysis of fingerprints can be improved, resulting in good results.
