Abstract:
An apparatus for increasing the resolution of at least one portion of a cryogenically cooled and vacuum-sealed infrared imaging detector including a two-dimensional detector array having a fill factor value, the portion of the array successively exposed to an image scene to acquire multiple infrared imaging samples of the scene, a masking filter having a single pattern, disposed between the array and the image scene and operative to reduce the fill factor value of the portion of the array by a fill factor reduction amount (FFRA), an optical element disposed between the masking filter and the image scene, a directional angle shifter for shifting an angle at which the imaging samples are directed onto the portion of the array thereby successively shifting the image scene relative to the portion of the array between each of the imaging samples by a shifting increment corresponding to the FFRA and a processor.

Claim (Index 8):
A method for increasing the resolution of at least a portion of a cryogenically cooled and vacuum-sealed infrared imaging detector comprising a two-dimensional detector array of photosensitive pixels arranged in a matrix, said detector array being operative within a wavelength range of 1-15 micrometers (\u03bcm), said detector array having a fill factor value, said infrared imaging detector comprising detector optics, comprising the procedures of:\n successively exposing said detector array to an image scene to acquire multiple infrared imaging samples of said scene; reducing said fill factor value of said at least one portion of said detector array by a fill factor reduction amount by masking part of an active region of at least one of said photosensitive pixels for each of said imaging samples, via a masking filter, having a single pattern, integrated with said detector array, such that only a sub-region of a pixel region of said image scene is imaged onto a corresponding masked photosensitive pixel of said detector array, said masking filter reducing a sensitivity of said at least one portion of said detector array due to said fill factor reduction amount; successively shifting said image scene relative to said at least one portion of said detector array between each of said imaging samples by a shifting increment corresponding to said fill factor reduction amount and smaller than an unmasked active region of a masked photosensitive pixel; compensating for said reduction in sensitivity of said at least one portion of said detector array by selecting an f-number of said detector optics in accordance with said fill factor reduction amount; and reconstructing an image frame from said acquired imaging samples, the reconstructed image frame having, for at least one portion of it, a resolution greater than the intrinsic resolution of said at least one portion of said infrared imaging detector by a factor defined by said fill factor reduction amount, wherein at least one masked photosensitive pixel of said infrared imaging detector receives partially over-lapping sub-regions in said imaging samples; and wherein said fill factor reduction amount is less than half of said pixel region thereby increasing said resolution above a Nyquist frequency of said two-dimensional detector array.
