Abstract: A light sensor system including a reference light source that moves in unison with a primary mirror and/or an inertial measurement device, and/or the reference light source is directed toward an obscured region of the light sensor system. The reference light source may allow for improved jitter compensation based on feedback of the reference light. The feedback may be representative of the elastic deformation of the optics and telescope optical axis. The improved jitter compensation may allow for the light sensor system (e.g., the housing and/or mirrors) to be built with less stiff materials, which can reduce the cost of manufacturing the present light sensor system compared to previously known optical sensor systems. In cases of high vibration levels which would otherwise degrade the resulting image quality after material stiffness property selections have been exhausted, the light sensor system may provide jitter compensation to improve video or still image quality.

Abstract: An apparatus includes a deformable mirror. The deformable mirror includes a reflective surface configured to reflect a high-energy laser (HEL) beam and to focus the HEL beam on a target. The deformable mirror also includes multiple actuators configured to adjust a shape of the reflective surface in order to maintain focus of the HEL beam on the target over a specified range of distances between the deformable mirror and the target. At least one portion of the reflective surface is configured to be adjusted by the actuators and obtain convex, flat, and concave shapes.
