英文摘要	Herein we propose a polarimetric imaging system that uses a microgrid polarizer placed on the conjugate point of two telecentric optical paths, matching large polarizers with small sensors and thus effectively decreasing optical crosstalk and increasing imaging accuracy. We define a new parameter used to construct the high-precision polarization vector transfer model under crosstalk. Using the equivalent surface of the detector, we establish the relationship between focal shift and crosstalk ratio and obtain a multi-physical coupling mathematical model that accounts for the crosstalk ratio, extinction ratio, sensor error, target vector, and imaging accuracy of the system. The relayed-microgrid polarimetric imaging system is anticipated to be able to help identify objects of interest for remote sensing and military applications. (C) 2020 Optical Society of America
