Imaging Crowd Surveillance System

Abstract

An instrument to test the feasibility of imaging weapons concealed in a person's clothing has been developed. A simple object-plane scanner, which records images on film, has been used with two sensors. The gallium arsenide photodetector has peak response at a wavelength of 0.285 mm and the indium antimonide free electron bolometer responds at wavelengths near 0.75 mm. The performance of this instrument is analyzed and potential improvements are suggested. The imagery obtained with the two sensors is compared.
