Abstract: A laser perimeter intrusion detection system which includes means for providing laser beam components for defining the perimeter of a predetermined geographical area to be protected. The system includes a sensing subsystem which is comprised of a plurality of sensors for providing electrical outputs from the sensors, the electrical outputs being responsive to interruption of any of the laser beam components. The system has an electrical signal-processing and logic subsystem for identifying the specific portion of the perimeter controlled by any of the laser beam components when the particular component is traversed by an intruder. Included are means for chopper-modulating the laser beam to increase the difficulty of compromising the system and to make the laser beam invisible to the human eye.

Abstract: A class of materials exemplified by mixed crystals of barium niobate and strontium niobate acts as a radiation detector by reason of the change in polarization resulting from the heating produced by an incident beam. This pyroelectric response is sufficiently rapid for infrared radiation that a pulse train well in excess of a megabit per second may be followed for incident beam power well below 1 watt.
