Patent number: 11128372Abstract: A system for processing optical signals comprising a reference optical signal transmission structure configured to receive an optical signal at a first input and to provide the optical signal at a first output to a photodetector. A delay optical signal transmission structure configured to receive the optical signal at a second input and to provide a delayed optical signal at a second output to the photodetector. A signal processor configured to receive a first electric signal corresponding to the optical signal and a second electric signal corresponding to the delayed optical signal and to generate an output as a function of the first electric signal and the second electric signal.Type: GrantFiled: June 9, 2020Date of Patent: September 21, 2021Assignee: ADVANCED PHOTON APPLICATIONS, LLCInventors: Michaelene Williams Sprague, James Anton Harder

Patent number: 9891099Abstract: There is provided in a first form, a system including a detector and a reflector disposed about and proximal to the detector, at least of portion of the reflector being disposed in front of the detector. The reflector is configured to reflect at least a portion of the radiation directed to the system at an angle greater than a first predetermined value onto the detector, and the system is configured so that at least a portion of the radiation directed to the system at an angle less than the first predetermined value directly impinges on the detector.Type: GrantFiled: July 29, 2014Date of Patent: February 13, 2018Assignee: Elbit Systems of America, LLCInventors: James Anton Harder, Michaelene Williams Sprague

Patent number: 7566865Abstract: This disclosure describes a temperature controlled photodetector. The disclosed detector can reach a temperature at which responsivity is maximized within a short time and with little wasted power. Furthermore, the photodetector prevents thermal gradients from developing across the detector so that the whole detector region has equivalent responsivity.Type: GrantFiled: February 19, 2008Date of Patent: July 28, 2009Assignee: Elbit Systems of America, LLCInventor: James Anton Harder
