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 1):
An apparatus for increasing the resolution of at least one portion of a cryogenically cooled and vacuum-sealed infrared imaging detector, comprising:\n a two-dimensional detector array of photosensitive pixels arranged in a matrix, said detector array having a fill factor value, said at least one portion of said detector array successively exposed to an image scene to acquire multiple infrared imaging samples of said scene, said detector array being operative within a wavelength range of 1-15 micrometers (\u03bcm); a masking filter, having a single pattern, integrated with said detector array and disposed between said detector array and said image scene, said masking filter operative to mask part of an active region of at least one of said photosensitive pixels, thereby reducing said fill factor value of said at least one portion of said detector array by a fill factor reduction amount, such that only a sub-region of a pixel region of said image scene is imaged onto a corresponding masked pixel of said at least one portion of said detector array; an optical element disposed between said masking filter and said image scene, said optical element positioned to direct said image scene onto said at least one portion of said detector array through said masking filter; a directional angle shifter for shifting an angle at which said imaging samples are directed onto said at least one portion of said two-dimensional detector array to thereby successively shift 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, wherein at least one masked photosensitive pixel of said detector array receives partially over-lapping sub-regions in said imaging samples; and a processor, operative for 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 an intrinsic resolution of said at least one portion of said infrared imaging detector by a factor defined by said fill factor reduction amount; 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; wherein said masking filter reduces a sensitivity of said at least one portion of said two-dimensional detector array due to said fill factor reduction amount; and wherein an f-number of said optical element is selected in accordance with said fill factor reduction amount to compensate for said reduction in sensitivity of said at least one portion of said two-dimensional detector array.
