1. A liquid crystal on silicon imager, comprising:

  • a backplane substrate;

    a reflective polarization electrode array, placed onto the backplane substrate, wherein the reflective polarization electrode array consists of a plurality of reflective polarization electrodes, and a pattern of each of the reflective polarization electrodes is configured in a planar arrangement having regularly spaced and electrically isolated gaps in parallel to each other;

    a planar liquid crystal cell, placed above the reflective polarization electrode array;

    a transparent conductive film, placed above the planar liquid crystal cell; and

    a transparent plate, placed on the transparent conductive film and facing incident light;

    wherein the reflective polarization electrodes are spatially regrouped into several groups, which have different micro structural patterns.
