Advanced Transducer Technology. Volume II. Survey of Transducers for Physical Security Sensors.
Abstract
This report documents the results of a survey aimed at the identification and evaluation of new materials or techniques which could potentially advance the state-of-the-art in intrusion detection and perimeter surveillance systems. The emphasis here is not on complete systems but is concerned for the most part with the transduction phenomena, that is, the conversion of some intrusion generated disturbances into an output signal. The targets of interest in considering sensors or transduction phenomena are vehicles and humans. The primary types of transducers which have been employed for the detection of these disturbances have been seismic, acoustic, magnetic, electromagnetic, infrared, pressure and ultrasonic sensors. The sources (1971-1976) used in searching for new developments included the International Aerospace Abstracts, Engineering Index, Scientific and Technical Aerospace Reports, STAR, Science Abstracts, Electrical and Electronics Abstracts, DDC computer search and other miscellaneous documents. Most of the papers selected for review and those which are reported in this document are refinements of previous types of detectors using new fabrication techniques, lower cost, improved ruggedness, lower power consumption, higher sensitivitiy or increased bandwidth. Areas discussed were concentrated on acoustic, magnetic, electromagnetic, infrared and pressure transducers. (Author)
