Image sensor with focal plane extraction of polarimetric information

—A novel focal plane imaging sensor capable of real time extraction of polarization information is presented. The imaging system consists of a photo array of 256 by 256 linear current mode active pixel sensors (APS). Analog processing circuitry is included at the focal plane for noise suppression and computation of the Stokes parameters. The imaging sensor was fabricated in TSMC 0.18μm process with 10μm pixel pitch and 75% fill factor and it was successfully tested. An array of micro polarizer is designed and fabricated separately and we are currently investigating different techniques for merging these two separate entities together. Experimental results from the image sensor and the micro polarization array are presented. Discussion on future possibilities of this work is also presented.
