Patent number: 11632507Abstract: When imaging bright objects, a conventional detector array can saturate, making it difficult to produce an image with a dynamic range that equals the scene's dynamic range. Conversely, a digital focal plane array (DFPA) with one or more m-bit counters can produce an image whose dynamic range is greater than the native dynamic range. In one example, the DFPA acquires a first image over a relatively brief integration period at a relatively low gain setting. The DFPA then acquires a second image over longer integration period and/or a higher gain setting. During this second integration period, counters may roll over, possibly several times, to capture a residue modulus 2m of the number of counts (as opposed to the actual number of counts). A processor in or coupled to the DFPA generates a high-dynamic range image based on the first image and the residues modulus 2m.Type: GrantFiled: January 18, 2022Date of Patent: April 18, 2023Assignee: Massachusetts Institute of TechnologyInventors: Michael W. Kelly, Megan H. Blackwell, Curtis Colonero, James Wey, Christopher David, Justin Baker, Joseph Costa

Patent number: 10893226Abstract: A digital focal plane array includes an all-digital readout integrated circuit in combination with a detector array. The readout circuit includes unit cell electronics, orthogonal transfer structures, and data handling structures. The unit cell electronics include an analog to digital converter. Orthogonal transfer structures enable the orthogonal transfer of data among the unit cells. Data handling structures may be configured to operate the digital focal plane array as a data encryptor/decipherer. Data encrypted and deciphered by the digital focal plane array need not be image data.Type: GrantFiled: June 7, 2019Date of Patent: January 12, 2021Assignee: Massachusetts Institute of TechnologyInventors: Michael W. Kelly, Brian Tyrrell, Curtis Colonero, Robert Berger, Kenneth Schultz, James Wey, Daniel Mooney, Lawrence M Candell
