Possibility of the use of wedges in overview surveillance systems
It is known that at the corners of the optoelectronic surveillance system's (OSS) more than 20° relative to the axis of the lens, the flat mirror optical-mechanical scanning system's size sharply increases proportionally to the scanning angle tangent. Therefore, to reduce the dimensions of opto-mechanical scanning system, improve the accuracy of scans, reduce the impact of vibrations there were suggested to browse space with optical deflector wedges instead of swinging mirror. A method for determining the maximum allowable angles of scanning optical wedges, which provides requirements for the angles of the sightings in modern OSS, was developed. The method is based on the maximum allowable chromatic scale wedges. Examples of calculating the maximum viewing angles of opto-mechanical scanning systems for imaging surveillance TV and infrared channel were considered. The angles of sight and fully meet the requirements of a modern land and air OSS.
