The use of interferometer to detect and analyze laser radiation is well known, but when the intense ratio of the laser radiation to the background natural light radiation is too small, the laser radiation cannot be detected. a novel more sensitive method for detect of wideband weak incident laser in strong background noise is introduced in this paper. the optical unit uses two wedge interferometers and two line array detectors. the incoming light radiation is divided into two beams and through the interferometers
在被動激光偵察告警中,對微弱脈沖激光信號的探測是一個難點。當探測距離相當遠或視場內接收的背景光輻射很強時,脈沖激光信號到達探測器的能量很小,會淹沒在強大的背景光信號中而探測不到。本論文提出了一種探測微弱脈沖激光信號的方法,可對強烈背景光中的激光威脅信號進行探測和告警,並給出其波長參數。The project adopts pulsed laser ranging in noncoherent detect mode, uses a 905nm pulsed laser diode as the laser source, detects object with a single apd, adopts an optics - mechanics scanner in object space to obtain images, and obtain distance images and intensity images of object simultaneously
