Abstract

High power laser transmission in optical system is a key link for laser coping with electro-optical imaging system. When laser goes through the entrance pupil of optical system, diffraction effect inevitably comes into being due to the limitation of the entrance pupil. The energy distribution on the photodetector caused by diffraction effect can have a serious impact on the target detection and recognition. The correction method of diffraction effect among the different optical systems has been proposed based on Fraunhofer diffraction theory in this paper. The simulations results have indicated that diffraction effect simulated by the oscillation envelope approximation have a good agreement with the results simulated by Bessel function on energy distribution profile and changing trend. The difference is the lack of fine modulation of sidelobes, but the modulation is lower than the sidelobes by 3 orders of magnitude. The agreement has proved that the correction method is practicable, which can effectively solve the effect estimation among the different types and F number of optical systems.
