Research on Detection of Gunshot Residues on Textile by Infrared Spectroscopic Imaging
Abstract
The different chemical components of gunshot residues and the corresponding carrier medium give rise to different spectroscopic features. By utilising this property, infrared spectroscopic imaging is employed to detect the gunshot residues on the surfaces of different textiles. Compared to traditional imaging methods, this technique produces higher-contrast images. Factors such as the composition of gunpowder, material burned, surface property of the carrier medium, range of excitation light, and starting and ending wavelengths are analysed. This research offers a novel idea for the detection of gunshot residues.
