  • POLARIZED LIGHT 3D IMAGE MEASURING INSTRUMENT AND MANUFACTURING METHOD THEREOF
    Publication number: 20210223107
    Abstract: An instrument for measuring polarized light 3D images and a manufacturing method thereof comprises an image sensor, a liquid crystal cell, and a polarizing plate. The polarizing plate comprises at least four quadrants and is disposed on top of the image sensor. When the polarization state of light is sensed, the image sensor captures and calculates four detection parameters to determine Stokes parameters S0˜S3, S0=I (0°, 0°)+I (90°, 0°), S1=I (0°, 0°), ?I (90°,0°), S2=2·I (45°, 0°)?S0, S3=2·I (45°, ?/2)?S0.
