Very high angular resolution laser beam rider detector having a gated image intensifier and a video camera

摘要: A laser warning receiver (LWR) having an ability to not only detect a low power level source, such as pulse train emitted by beam rider, but also provide high angular resolution in determining the angle of arrival that train. The includes lens/filter arrangement for large area photodetector incoming signal from emitting source and gain amplifier amplify which is then applied synchronization generator generates digital with pulses corresponding peaks signal. code breaker where analyzed further generated anticipating order verify code. That time gate generate code, synchronized signal, controls voltage gated image intensifier coupled video camera. Gating synchronized, result, coded emissions so camera can be displayed on monitor more easily differentiated background. width generator, camera, intensifier, auto-iris zoom lens are all under control processor.
