Optimization of CCD-Based Gated-Viewing System for Low Illumination Conditions

This paper considers the problem of low radiation flux in implementing the gated-viewing device based on CCD image sensor without the use of an image intensifier. Special way to control the sensor in low illumination conditions is performed. The way allows building of a gated-viewing system without an image intensifier which is traditionally used qua fast shutter. As the result the system can be smaller and lighter. The experimental testing of the gated-viewing system based on the offered method of CCD image sensor controlling showed its performance in conditions of ambient light less than 10 lux. The lower limit of the device sensitivity depends on the specific image sensor.
