Abstract: Aspects are generally directed to multi-sensor boresight alignment methods and systems for a multi-spectral reimaging optical system. In one example, a multi-sensor boresight alignment system includes a system interface to receive a first image frame from a first sensor and a second image frame from a second sensor, the first image frame having a contrast within a first spectral band and including a first image of a plate having a pattern of apertures, and the second image frame having a contrast within a second spectral band and including a second image of the plate. The system includes a field programmable gate array (FPGA) coupled to the system interface, the FPGA configured to spot track each image frame to identify a corresponding centroid of the pattern of apertures and correct an optical alignment between the first and second sensors based on a position of the corresponding centroids.

Abstract: A beam director system includes a high-energy laser (HEL) beam source for an HEL beam, a primary mirror disposed along an optical path downstream of the HEL beam source, output optics downstream of the primary mirror, an auto-alignment system associated with the HEL beam source, a jitter correction system downstream of the HEL beam source and upstream of the primary mirror, and a burn-through detector associated with the primary mirror.

Abstract: A beam director system for a high-energy laser (HEL) weapon includes correction sensors that are able detect misalignments in optical elements throughout the entire optical path traversed by the high-energy laser. The system includes beam correction sensors that sense misalignments in a first part of the optical path, and high-speed track sensors that sense misalignments in a second part of the optical path, with the first part and the second part overlapping. This allows all optics to be sensed by the beam correction sensors and/or the high-speed track sensors. The system can accommodate a wide variety of lasers for the HEL, preferably including a co-boresighted and aligned alignment laser. By having the track sensors further downstream on the optical path than in prior devices, the acquisition and track sensor fields of view of the system may be improved.

Abstract: Aspects are generally directed to an alignment assembly and method for aligning a multi-spectral optical system. In one example, an alignment assembly includes an illumination source configured to emit illumination in a first spectral band, and a first plate having a plurality of apertures formed in a reflective surface thereof. The reflective surface of the first plate is disposed to reflect the illumination emitted by the illumination source. The alignment assembly may also include a second plate positioned proximate to the first plate and spaced apart from the first plate to define a gap between the first plate and the second plate, the first plate being interposed between the second plate and the illumination source, and a heating element coupled to the second plate and configured to heat the second plate to emit thermal infrared radiation, from the second plate, in a second spectral band.

Abstract: Electronically derotating a picture-in-picture video source can be used to independently derotate a secondary video source separate a primary video source. A method of electronically derotating a picture-in-picture image are described herein, the method comprising processing a first image having a first image primary axis; processing a second image having a second image primary axis; derotating the second image around the second image primary axis to align the second image primary axis substantially parallel with the first image primary axis; and displaying the first image and the second image on a display.
