Patent number: 9325883Abstract: A multi field of view (FOV) imaging system is disclosed. In one embodiment, a dual FOV imaging system includes a composite lens array including a first lens set positioned to focus a first type of FOV and a second lens set positioned to focus a second type of FOV and a composite focal plane array (FPA) including multiple focal plane arrays (FPAs). Further, the composite FPA is disposed at the first type of FOV and the second type of FOV for producing a seamless mosaic dual FOV image of a target region.Type: GrantFiled: September 6, 2012Date of Patent: April 26, 2016Assignee: BAE Systems Information and Electronic System Integration Inc.Inventors: Dennis P. Bowler, Steven J. Wein, David J. Korwan, James D. Targove, Gerard M. Perron

Patent number: 9310668Abstract: Techniques and structures to facilitate efficient replacement of windows/domes of optical systems, such as turreted pointer/tracker systems and seekers and other such gimbal-based or fixed targeting systems. The techniques can be implemented, for example, in a mounting ring or bezel, wherein the dome/window center of curvature is actively aligned during assembly to a reference feature on a mounting bezel during the dome-to-bezel alignment. This reference feature then mechanically registers the dome-bezel assembly to a given chassis. In some embodiments, the techniques allow for positioning of a replacement window/dome on an optical lens system, such that co-boresight of multiple beam paths is automatically maintained.Type: GrantFiled: April 17, 2012Date of Patent: April 12, 2016Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: David J. Korwan, Bruce W. Baran, Glenn Sindledecker, Gerard M. Perron, Edward M. Kolvek

Patent number: 8867140Abstract: A compact, lens suitable for airborne photography and mapping has distortion less than 0.6% and is athermal from ?15° C. to +40° C. The lens is near-telecentric to less than 11°, apochromatic over the wavelength range 450 nm-650 nm, and has a full field of view of 60° (high quality field over 53°). The lens can be secondary color corrected. In embodiments, the focal length is 101 mm and the back working distance is more than 10 mm. Embodiments have a focal plane diameter of 104 mm and are compatible for use with a CMOS 1.8 gigapixel multiple FPA. In embodiments, the lens comprises three groups of optical elements, with an aperture located within the second optical group. In some embodiments the first group includes two elements, the second group includes six or seven elements, and the third group include three elements. In embodiments the lens (without window) is less than 180 mm long.Type: GrantFiled: August 22, 2011Date of Patent: October 21, 2014Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Mark L Oskotsky, Michael J Russo, Gerard M Perron, David J Korwan

Publication number: 20030231390Abstract: An athermalized delay line having two optical paths whose difference in optical path length is thermally insensitive. Each optical path typically includes a reflecting quarterwave plate, each path being fed by the output from a polarizing beamsplitter. The delay line is suitable for incorporation into a PMD compensator having at least one compensation stage formed from a polarization controller and an athermalized delay line.Type: ApplicationFiled: March 14, 2003Publication date: December 18, 2003Inventors: Steven J.
