Polarization Image Sensor for Highly Sensitive Polarization Modulation Imaging Based on Stacked Polarizers

In this article, We demonstrated an image sensor for detecting changes in polarization with high sensitivity. For this purpose, we constructed an optical system with a two-layer structure, comprising an external polarizer and polarizers on a pixel array. An external polarizer is used to enhance the...
