Research On Reflection Wave Of Incidence Laser In Military Optical Instruments

The principle and experimental technique of hiding optical instruments detection based on "Cat's eye" effect are described in this paper. The factors that influence the intensity of the reflection wave were analyzed both quantitatively and qualitatively with the method of ray tracing. Research results show that the incline and defocusing of reflection plane in optical instrument (such as telescope and camera) reduce the intensity of the "Cat's eye" reflection., The conditions of "Cat's eye" effect used for detection are very difficulty because of these affect factors.In addition, this paper reported the phenomenon of reflection wave and "Cat's eye" effect experiments with level and aiming telescope. The experiment' results show that the results of theoretical calculation are agree with fact basically.
