A view for security: Thermal imagers

The use of thermal imagers in everyday security applications has been, until recently, very limited. The last several years have seen an increased use of existing military inventory and commercial imagers to satisfy a variety of security and surveillance needs. This paper discusses the recent history of applying today's available thermal imagers to security-related problems. It discusses the problems, the deficiencies of existing imagers to solve those problems, and summarizes the current status of imagers applied to security and suggest imager features which would make them more useful to security applications. 2 refs.
