Patent number: 9894292Abstract: 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.Type: GrantFiled: May 5, 2013Date of Patent: February 13, 2018Assignee: ELBIT SYSTEMS ELECTRO-OPTICS ELOP LTD.Inventors: Shalom Binder, Dov Frieman, Avishay Nachum

Patent number: 8792170Abstract: 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.Type: GrantFiled: March 4, 2010Date of Patent: July 29, 2014Assignee: Elbit Systems Electro-Optics Elop Ltd.Inventors: Isac Boubis, Dov Frieman, Avishay Nachum
