Research on polarization-low level integrated imaging technology based on EMCCD

Multi-dimensional information acquisition by single detector is the future direction of photoelectric detection. Aiming at the problem that the energy and the polarization information could not be considered in target detection, a new pixel array structure with polarization-low level light integrated function was proposed. The integration of polarization and low level light detection was realized in electronic multiplying charge coupled device (EMCCD) by introducing the white light channel and the reduced polarization channel. The experimental results show that under the low level light condition, the high sensitivity of the new detector is held, and the imaging quality at low illumination is almost not decay. In polarization mode, the white light channel and two polarization angle enable the detector to obtain enough polarization information, so as to realize the polarization detection of the target. Synchronous acquisition of high sensitivity imaging detection and polarization information detection by this method is realized, and the reconstruction of the detection mode can be realized by the algorithm processing.
