Method for displaying super-resolution video of at least one-moving object without image artifacts, including the procedures of acquiring microscanned images of at least one moving object, a first and second subset of the images respectively forming a first and second data set, for each data set, analyzing at least a portion of the sub-set of the images for spatial and temporal information, determining a respective movement indication of the moving object according to the spatial and temporal information, in parallel to the procedure of analyzing, forming a respective super-resolution image from each data set and designating a respective bounded area surrounding the moving object, and repeatedly displaying each super-resolution image outside the bounded area a plurality of times at a video frame rate and displaying during those times within the respective bounded area, a plurality of consecutive microscanned images of the moving object at the video frame rate.

Systems and methods for enhanced motion detection, object tracking, situational awareness and super resolution video using microscanned images

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.

Infrared detector with increased image resolution

Apparatus for increasing resolution of cryogenically cooled vacuum-sealed infrared imaging detector. A two-dimensional detector array of photosensitive pixels is successively exposed to an image scene, acquiring multiple imaging samples. A masking filter, disposed between the detector array and image scene focal plane, is maintained at a fixed position with respect to the detector array, and reduces the region of pixels collecting incident radiation for each imaging sample such that only a portion of each pixel area of the image scene is imaged onto the corresponding detector array pixel. Shifting means successively shifts the optical path of the image scene relative to the masking filter, by a shifting increment or fill-factor reduction amount equal to a fraction of the array pixel width, to image different sub-pixel regions in each imaging sample. A processor reconstructs an image frame having a resolution greater than the intrinsic detector resolution by the fill-factor reduction amount.

Infrared detector with increased image resolution and method for use thereof

Imaging device and method, the device including receiver optics, a diffractive and focusing surface, and a pair of diffractive and focusing arrangements, the receiver optics receiving radiation including a first wavelength selected from a first spectral band, and a second spectral band, where the first wavelength is substantially a multiplicative factor less than the midpoint of the second spectral band, the diffractive and focusing surface diffracting the first wavelength at an order of diffraction substantially equal to the multiplicative factor, and diffracting the second spectral band at a first order of diffraction, each of the diffractive and focusing arrangements diffracting, in turn, the first wavelength at a first order of diffraction, such that the first wavelength and the second spectral band emanating from the second diffractive and focusing arrangement focuses at a substantially common focal length and at a substantially common focal plane width.
