Abstract:

Short-wavelength infrared(SWIR)focal plane array detector suffers from problems including intrinsic non-uniformity, low signal-to-noise ratio(SNR), and relatively high cost. To overcome these difficulties, a staring-mode frame imaging scheme was proposed based on Hadamard transform(HT), using single element detector and digital micro-mirror device(DMD)spatial light modulator. Experimental study has been carried out to verify the validity of this method in SWIR imaging. The results demonstrate that this scheme is a promising approach to achieving low cost, high SNR SWIR imaging.
