Abstract
- Spatially modulated full polarization imaging is the method of modulating the polarization information of a target into a single interferogram, which has a good real-time feature. Since polarization modulation lenses are made of birefringent crystals, they will produce chromatic dispersion. Therefore, the interference fringes on the interferogram will become blurred, affecting the subsequent demodulation processing. It is necessary to determine the bandwidth limit of the incident light. Based on these considerations, this paper analyses the distribution of the polarization information in the frequency domain and proposes a method of determining the bandwidth limit based on the pixel size in the frequency domain.
