ABSTRACT:
A thermal detection and alarm system for indicating the irradiation of a surface by a heat source such as a laser beam has been invented. The detector element may form an integral portion of the vehicle's outer surface or may be parasitically mounted thereto. The proposed system is light weight, energy efficient, durable and highly sensitive. The invention is especially suited for use with Boron-Tungsten composite surfaces as found on aircraft and spacecraft.
