Infrared is the second most intense radiation band in our environment and its detection and imaging have extensive industrial,military,and commercial applications.[1] Up to now,different types of IR detectors have been developed.[2] However,the limiting factors to wide use of IR imaging have been the high cost of IR cameras and the high power consumption required for detector cooling and readout electronics.Our group is aiming at overcoming these limitations by developing a low cost,high performance uncooled focal plane array (FPA) with a low power,noncontact optical readout.
