    • Abstract:
      The use of infrared radiation for the detection of concealed metal objects has been investigated both theoretically and experimentally. The investigation was divided into two phases, one which considered passive techniques, and another which involved active sources of radiation to probe the subject. Because of the limited amount of time and equipment available, only primitive systems were studied, but the results serve as a fundamental guide to the requirements of a field operational system. The results obtained show that metals concealed by clothing can definitely be detected by observing the far infra-red radiation from the region of the hidden object. This type of system has the very attractive feature of high spatial resolution, and can easily distinguish between dangerous weapons and harmless objects.
