Abstract
The spatially modulated full polarization imaging technology can simultaneously acquire the target full polarization parameter, and the spectral aliasing and interference intensity existing in the polarization information demodulation result in low spatial resolution and false information in the frequency domain reconstruction target image. The polarization component images are reconstructed and restored by selecting filters of different bandwidths and matching the adaptive filters. The experimental results show that under different filter bandwidths, the system exhibits different modulation spectrum characteristics and is matched by filters. The design improves the image reconstruction restoration effect and provides reference for polarization detection and analysis research.
