    Abstract: An apparatus for increasing the resolution of at least one portion of a cryogenically cooled and vacuum-sealed infrared imaging detector including a two-dimensional detector array having a fill factor value, the portion of the array successively exposed to an image scene to acquire multiple infrared imaging samples of the scene, a masking filter having a single pattern, disposed between the array and the image scene and operative to reduce the fill factor value of the portion of the array by a fill factor reduction amount (FFRA), an optical element disposed between the masking filter and the image scene, a directional angle shifter for shifting an angle at which the imaging samples are directed onto the portion of the array thereby successively shifting the image scene relative to the portion of the array between each of the imaging samples by a shifting increment corresponding to the FFRA and a processor.

    Abstract: A system and method for analyzing quality criteria of a radiation spot are provided herein. The system may include: at least one controllable electromagnetic radiation source configured to generate and transmit a radiation beam onto an object, resulting in a radiation spot on said object; at least one radiation sensor configured to sense and obtain radiation reflections coming back from said object, wherein the radiation beam is generated in a way that reflections from different ranges are distinguishable of each other; and an analyzer configured to analyze said radiation reflections, and determine a remedy to the radiation beam, in a case that said radiation spot does not meet predefined spot validity criteria. The method may implement the aforementioned logic in a different architecture.

    Abstract: Aspects of embodiments pertain to beam combining devices for coherent and spectral beam-combining. The coherent beam combining (CBC) device may comprise a monolithic body having an input surface and an output surface. The input surface may be configured to direct a plurality of coherent entering optical beams through an optical pathway inside the monolithic body towards the output surface; and a phase mask configured for combining beams, exiting from the output surface of the monolithic body, to form a single combined output beam. The Spectral beam combining (SBC) device may include a monolithic body configured to direct the entering optical beams through a multi-diffraction optical pathway inside the monolithic body by directing the entering optical beams such as to impinge a diffractive surface thereof at least twice, for combining the entering optical beams into a single multispectral combined output optical beam. Embodiments may also include methods for cascaded beam combining, using multiple combining devices in a network configuration.

    Abstract: Multi-Channels coherent beam combining (CBC) using a mechanism for phase and/or polarization locking that uses a reference optical beam and an array of optical detectors each detector being configured and located to detect overall intensity of an optical interference signal caused by interfering of the reference beam and a beam of the respective channel, where the fast intensity per-channel detection allows simultaneous and quick phase/polarization locking of all channels for improving beam combining system performances.
