Polarization Reconstruction for the DoFP Sensors With a Siamese Decoupling Network

The division of focal plane (DoFP) polarimeters are often used in polarization imaging sensors. However, they provide exceptional efficiency at the expense of resolution. The high-performance approach in polarization reconstruction is a challenge because of the inherent ill-posed nature of reconstruction tasks. We believed that this ill-posed nature mainly derives from the non-restricted solution space. Reducing this is helpful in using models to find more correct mappings. Therefore, a polarization reconstruction strategy with a Siamese decoupling network is proposed in this letter. The findings demonstrate that this model achieves good results, with a peak signal-to-noise ratio of 56.53, outperforming the previous state-of-the-art results. The proposed network can be used for various applications, such as crystallite analysis, remote sensing, microorganism imaging and cytologic diagnosis.
