Portable hyperspectral imager with continuous wave green laser for identification and detection of untreated latent fingerprints on walls

Highlights • The portable HSI combined with CW green laser is a practical tool in crime scenes. • The CW green laser is superior to CW blue and yellow lases in the present method. • Spectral separation based on HSD of doubly overlapped prints is also practical.
