Optical Systems, Inc.

Irwin Kaplan

An above-the-water system for and method of finding targets, both animate and inanimate, in a marine environment, especially by determining the distance and depth of targets at, above or below the surface of, the water. An optical transmitter transmits infrared and ultraviolet light beams toward different zones of coverage on the water. An optical receiver equipped with a segmented detector separately detects return target reflections. An indicator, including range and depth indicators, provides information as to the distance to the target and, if it is below the water, its depth. A rotating deviation prism increases the target search area.
