Abstract
In this paper, the feasibility of monitoring the objects located at a distance (up to 5 m) from a brightness amplifier in a monostatic laser monitor is demonstrated. The experimental study of the dependence of the quality of the obtained images on the distance between the object and the brightness amplifier is presented. It is shown that the time delay between the initial moment of the ASE pulse and the moment when the input signal is brought to the input of the brightness amplifier significantly specifies the image contrast at its output. A scheme that allows us to obtain high image contrast of objects located at a distance from the brightness amplifier is proposed.
