Gated-Viewing System with an Electronic Shutter on a CCD Image Sensor

Abstract

The results of the development and experimental investigation of the gated-viewing method without the using an image intensifier as a fast shutter are presented. The device for implementing the method consists of an interline CCD image sensor with an input lens and 906 nm pulsed laser diode with an output lens that forms an illumination beam. The gated-viewing method is based on the original CCD control procedure, which allows observing multiple pulses without lowering the frame rate. Experimental studies have shown the method feasibility under conditions of smoke and fog.
