Abstract :
This study focuses on the detection of muzzle flash detection of small arms using low cost silicon CMOS-based sensors and imagers. Two types of sensors are utilized: CMOS Image Sensors and CMOS-SPADs (Single Photon Avalanche Diodes). The detection approach is based on Near-Infrared (NIR) spectral features of muzzle flash originating from alkali metal flash suppressing additives in the gun powder. The spectral signature around wavelength of 760nm allows achieving adequate signal to noise ratio even in day light.
