Abstract: A system for measuring movement of an object includes a source of light for emitting a beam; an object for receiving the beam from the source and reflecting the beam; and a reflective optic for receiving the beam reflected from the object and again reflecting the beam at a first angle. The system also includes a receiver for receiving the reflected beam from the reflective optic. When the object moves in distance, the reflective optic reflects the beam at a second angle. The reflective optic may be replaced by an equivalent refractive optic(s). The receiver measures movement of the object, based on a difference between the first angle and the second angle. The reflective optic may include a cylindrical reflective optic, or a spherical reflective optic. The refractive optic(s) may include a plano hemispheric refractive optic, or a meniscus refractive optic. The receiver may include a quad-cell imaging system, or a focal plane array (FPA). The source of light may include a laser, or any collimated beam source.

Abstract: An optical imaging system includes a non-gimbaled telescope attached to a platform configured for outer-space orbit. Attached to the platform is a coelostat that is positioned in front of the aperture of the telescope. The coelostat includes two connected mirrors. Mirror one receives light from a scene of interest and mirror two receives light from the first mirror and transfers that light to the aperture of the telescope. The coelostat rotates 360 degrees around the azimuth axis. Additionally, mirror one rotates around the elevational axis to provide the entire system with a large field of regard.

Abstract: There is disclosed a method of enhancing an image of a scene. The method divides the image into a plurality of frequency zones, and performs a plurality of Richardson and Lucy (RL) iterations of each of the frequency zones to obtain an enhanced image of the scene. The frequency zones and the plurality of RL iterations are determined using a Taguchi orthogonal array computation that minimizes radiometric errors in the enhanced image. The image may be Rayleigh sampled image obtained by a Rayleigh sampling system. A truth scene is not needed to use the method.

Abstract: An optical sensor is disclosed of the type typically including an optical system for focusing light onto a focal plane. The optical system having a predetermined Numerical aperture which provides a corresponding level of spatial resolution. The optical sensor also including detectors for converting the light focused onto the focal plane into electrical signals including imaging data. The optical sensor further including a processor which processes the imaging data in order to provide a desired level of spatial resolution which is substantially higher than the corresponding level of spatial resolution.
