According to the principle of polarized light interference, the change of the rotating direction of incident light and circular polarizer when the circular polarization filter is reversed is analyzed. The circular polarizer and the linear polarizer are combined and the 14 wave plate is positioned between the linear polarizer and the spectral transmittance curve of the linear polarizer and the circular polarizer relative rotation to different azimuths is measured. When the polarized light emerges due to the interference of polarized light, the corresponding intensity and chromaticity change appear as a model, and the photographic performance of the circular polarizer when it is used in reverse is studied and summarized.
