Laser spot quality is one of the important indicators of laser weapons. Laser spot quality inspection has important significance for the development of laser weapons. In order to adapt to the characteristics that high temperature is difficult to measure directly of focused spot of laser weapons. A method of using a polarizing plate to attenuate the light intensity and a CCD to capture a spot image is put forward. The intensity decay rate of the polarizer group is studied. A experiment system is established to analyze the attenuation of the high-temperature light spot by the polarizer group.Theoretical analysis and experimental results show that the polarizer group can perform high-order attenuation of high-temperature light spots. This provides a theoretical basis for laser flare detection and attenuation system.
