Research on Trace Analysis Based on Hyperspectral Field

Hyperspectral technology has the dual characteristics of imaging and spectroscopy at the same time. The use of hyperspectral technology for on-site trace inspection and identification can have a good effect. It can not only show the traces of on-site crimes, but also conduct inspection and identification for trace evidence, and identify substances. Evidence is analyzed and explained in a comprehensive and meticulous manner, so as to promote the further investigation of the case. This article uses hyperspectral technology to analyze the substance traces at the crime scene: blood, handwriting, fingerprints, footprints, etc., and emphasizes the value and significance of hyperspectral technology in criminal investigation work.
