Abstract

We present an integrated polarization image sensing architecture, which can be used for measuring all the Stokes parameters, and then regulating the polarization state of light beam according to the polarization state we have known, by changing the voltage amplitude applied over the patterned electrodes. The architecture contains a liquid crystal (LC) device and an uncooled photo detector. We can calculate the polarization state of the polarized light beam by the intensities of the light passing through the different area of the LC device, and then modulate the polarization state of the light beam to other polarization state which we want by only varying the voltage amplitude of the driving signal in sub-millisecond. In this paper, we will give the simulating results of the polarimeter architecture we designed.
