Abstract
The use of holographic optical elements (HOEs) to discriminate between coherent irradiation and broadband, noncoherent light has been experimentally demonstrated under adverse scattering and attenuating conditions. As a passive sensor component in a laser irradiation detection system, an HOE can be used in several application areas, e.g., data transmission systems, aircraft warning system, underwater communications, and alignment systems, where wavelength and direction of arrival information can be used. The efficient concentration or focusing of laser light by an HOE onto a detector stage and, of equal importance, the ability to form bright, unique geometric patterns are characteristics that establish the HOE's use as a readily compatible irradiation sensor component. In addition, there is a considerable size and weight advantage over other functionally comparable optical components. Finally, as a passive element, an HOE can fmd use with CW or pulsed illumination. The properties and advantages, pros and cons, of the use of HOEs as sensor elements are discussed in the paper and illustrated in several laboratory experiments and a field test.
