Abstract: A scan mirror reflectivity calibration device is provided for monitoring and calibration of a rotating two-sided scan mirror. The scan mirror reflectivity calibration device can comprise at least one light source assembly operable to direct light onto a back side of a rotating two-sided scan mirror. The at least one light source assembly can be mounted outside a swept volume of the rotating two-sided scan mirror. The scan mirror reflectivity calibration device further comprises at least one detector assembly operable to detect light that is emitted from the at least one light source assembly and is reflected off of the back side of the rotating two-sided scan mirror. The at least one detector assembly can be mounted outside the swept volume of the rotating two-sided scan mirror.

Abstract: A system and method for measuring and removing jitter from an optical sensor includes a jitter stabilization system and at least one focal plane array. The jitter stabilization system is positioned at a shared focus of the focal plane array, which can be generated by an optical imager. A jitter signal of the jitter stabilization system makes a double pass through the system, contacting every reflective surface along the optical path within the system, before returning to a position sensing detector (PSD).

Abstract: According to an embodiment of the disclosure, an optical sensor system comprises a mast, a mast mirror, a navigation unit, one or more faceted mirrors, and at least two beam-steering mirrors. The mast is elevated from a vehicle. The mast mirror reflects signals either to or from object space along a line of sight. The navigation unit determines a location and attitude of the mast mirror. The one or more faceted mirrors reflect an error sensing beam to reveal a flexure of the mast mirror. The at least two beam-steering mirrors prevent the line of sight for the signals reflected off the mast mirror from walking off the mast mirror by adjusting an angle and translation of the signals reflected off the mast mirror.

Abstract: A multi-function sensor system including an auto-alignment system. The multi-function sensor system includes a laser module configured to provide a transmit beam and an auto-alignment beam, a shared aperture component, a first channel configured to direct the transmit beam and the auto-alignment beam to the shared aperture component, a second channel configured to receive the transmit beam from the shared aperture component and provide a receive beam to the shared aperture component, and a third channel including a passive imager configured to receive the auto-alignment beam and a first portion of the receive beam from the shared aperture component, wherein the auto-alignment beam propagates through the passive imager to provide an indication of a line of sight (LOS) of the transmit beam relative to a field of view (FOV) of the passive imager.

Abstract: A LADAR system includes a transmitter configured to emit a directed optical signal. The LADAR system includes a shared optical aperture through which the directed optical signal is emitted. The shared optical aperture includes a first pupil plane. The shared optical aperture receives a return optical signal that is based on the directed optical signal. The system includes a mirror with a hole through which the directed optical signal passes. The mirror also reflects the return optical signal towards an imager. The imager receives the return optical signal and generates an image. The image is based on a portion of the return optical signal. The system also includes a partial aperture obscuration at a second pupil plane. The partial aperture obscuration may block a portion of internal backscatter in the return optical signal. The system also includes a focal plane to record the image.

Abstract: An optical system including a unity magnification, finite conjugate, all-reflective image relay configured to receive optical radiation representing an input image and to relay the optical radiation via five reflections to an output image plane to provide an output image at the output image plane, the output image being a unity magnification copy of the input image. In certain examples the optical system includes foreoptics configured to produce the input image. The foreoptics and the image relay can be telecentric.

Abstract: A five-mirror all-reflective afocal anastigmat. In one example, a five mirror afocal anastigmat includes five mirrors arranged to sequentially reflect from one another electromagnetic radiation received via a system entrance pupil to produce a collimated output beam of the electromagnetic radiation at a system exit pupil, the five mirrors consisting of three positive-powered mirrors and two negative-powered mirrors, wherein optical powers of the five mirrors are balanced to achieve a flat field condition at the system exit pupil.
