Full Stokes polarization correlated imaging
In recent years, with the rapid development of associated imaging technology, it has been widely applied in many fields and has attracted great attention. The polarization detection technology can distinguish different material objects and enhance the system ability of detecting and identifying. In this paper, with the advantages of polarization detection techniques and associated imaging techniques, the Walsh-Hadamard speckle was used to illuminate the scene, the scene reflection light was detected by time-sharing polarization, and the full Stokes polarization correlation imaging of the scene was realized. The corresponding experimental system was set up, and the imaging experiments of multi-material objects were carried out. Using the signals of different polarization states and illumination speckles, the Stokes parameters images of objects were obtained by calculating. The distinguish of different material objects and the objects with the same material and different structures in the same scene were realized. Through the evolutionary compression sampling recovery technology, the images were restored at different sampling ratios. The results show that the evolutionary compression sampling recovery technology can restore clear full polarization information at a lower sampling rate.
