Abstract: There is provided in a first form, a detector. The detector includes a photosensitive detector element; and a reflecting surface disposed about and proximal to the photosensitive detector element, wherein the reflecting surface is configured to reflect radiation impinging on the reflecting surface onto the photosensitive detector element; and wherein the reflecting surface is further configured to determine a field of regard greater than a predetermined field of view.

Abstract: 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.

Abstract: 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.
