Abstract: A system for forming virtual beacons usable in wavefront sensing includes a first lens configured to receive light from a target and to output an image towards an input plane. The system also includes a selector positioned at the input plane. The selector includes a transparent portion that allows a portion of the image output by the first lens to pass through the selector to form a virtual beacon. The selector also includes a translucent portion to prevent another portion of the image output by the first lens from passing through the selector.

Abstract: An optical image amplifier device capable of amplifying low-intensity backscattered illumination includes an optical port having an input, an output, and a controller having an ON state and an OFF state, the controller connecting the input and the output to form an optical loop in the ON state and disconnecting the input and the output in the OFF state, and an optical relay housing the optical loop and connected to the optical port having a gain medium configured for amplifying a signal beam propagating inside the optical loop in the ON state.

Abstract: According to an exemplary embodiment of the present invention, an optical measurement apparatus includes a raster-mirror, an objective element, and a detector element. The raster-mirror includes a plurality of mirror segments that are articulated relative to adjacent mirror segments and configured to receive light from a portion of a field of view and provide a reflected light portion, where the plurality of reflected light portions comprise a reflected beam. The objective element is configured to receive the reflected beam and provide an objective beam having a plurality of objective beam portions corresponding to the plurality of reflected light portions. The detector element includes a plurality of detector portions and is configured to receive the objective beam and provide a corresponding image signal, where the plurality of objective beam portions are simultaneously imaged on the plurality of different detector portions.
