Searching for new optical testing method of forensic science and broadening application range of spectral imaging technology. Academic papers and documents were collected to master advanced tendencies about spectral imaging domestic and overseas in forensic science area. Experimental were conducted to prove the ability of spectral imaging in testing difficult physical evidence. Spectral imaging technology can successfully solve various evidence identify problems including fingerprints, writing material, trace evidence and biologic evidence. According to the results of experiment, spectral imaging has strong ability in forensic science field. Spectral imaging technology which has widely research space and important practical applications will open up a new optical testing method in forensic science.
