Detection technology of polarization imaging, which can detect the polarization state of light emitted or reflected from targets, has potential applications in space target detection and remote sensing. There are two methods for polarization state detection: time-sequential polarization detection and simultaneous polarization detection. In contrast with the well-studied time-sequential acquisition systems, the Simultaneous Imaging Polarization (SIP, one kind of simultaneous polarization detection) is a novel type of polarization imaging technology which is attracting more and more research interest. Since the polarization intensity images of 0，45，90 and 135 degrees from the same target can be simultaneously obtained on one detector, false polarization effects being introduced by targets' rapidly motion is avoided, which is difficult in time-sequential polarization detection system.There are seven major contributions in this paper. First, we gave a briefly introduction about the detection technology of imaging polarization. Second, the polarization detection principle of SIP detection system was presented.In the third part, the design of SIP experimental setup was showed. In the fourth part, we introduced image registration of the instrument in derail. The calibration of the instrument was shown in part five. Specifically, the depolarization of the instrument was calibrated by integrating sphere and the precision of polarization detection was tested by Variable Polarization Light Source (VPLS). The sixth part showed the polarization measurement results and their discussions.Finally, the conclusions and further improvement of this system were presented in the seventh part.

Polarimetric imaging allows for the vector nature of optical information across a scene to be obtained, with recent applications ranging from remote sensing to microscopy. In polarimetric microscopy in particular, different polarization states are conventionally achieved under time-division multiplexing strategies and are mainly subject to static phenomena. In the present work, we propose a cost-effective technique for polarization sensing with the possibility of real-time imaging microscopy. By modifying a commercial camera and replacing the conventional lens with an optical system that integrates a microscope objective and a lenslet array with a polarization mask, linear Stokes parameters can be obtained in a snapshot. The proposed scheme is robust against misalignment and suitable for handling video sequences of microscopic samples. To the best of our knowledge, this is the first report on combining multi-view sensing and polarization imaging for applications to microscopy.

High-resolution, wavefront-sensing, full-field polarimetry of arbitrary beams using phase retrieval

et al. 2022

Recent advances in structured illumination are enabling a wide range of applications from imaging to metrology, which can benefit from advanced beam characterization techniques. Solving uniquely for the spatial distribution of polarization in a beam typically involves the use of two or more polarization optics, such as a polarizer and a waveplate, which is prohibitive for some wavelengths outside of the visible spectrum. We demonstrate a technique that circumvents the use of a waveplate by exploiting extended Gerchberg–Saxton phase retrieval to extract the phase. The technique enables high-resolution, wavefront-sensing, full-field polarimetry capable of solving for both simple and exotic polarization states, and moreover, is extensible to shorter wavelength light.
