Parameter testing system for laser-beam riding guided sighting instrument

In order to meet the practical needs of laser-beam riding guided sighting instruments which can be tested overall indoor, a parameter solution in the testing system is demonstrated to test the performance parameters. Each part in the parameter testing solution is discussed separately. The system can test the parallel error of the fixed focal length between laser axial and sighting axial, the typical position output characteristic of a controlling field, the biggest parallel error in the whole process of zoom, and the irradiance uniformity of a laser spot by applying the technique of CCD image processing. The system has advantages in simple structure, convenient operation, high accuracy and so on. In the analog test, the solution of the system meets the challenge of practical needs in engineering.
