摘要： A system and method for imaging far away fast moving objects such as satellites in low earth orbit. The object to be imaged is illuminated simultaneously with a composite beam comprised of a large number of separate laser beams from a large number of laser sources each from a separate position with each of the separate laser beams shifted in frequency with respect to each other beam so as to produce a large number of beat frequencies in the composite beam. The positions of the laser sources are changed rapidly during an illumination period of a few seconds. Light reflected from the object is collected in a large number of light buckets and information defining the intensity of the collected reflected light as a function of time is stored. The positions and frequencies of each of the laser sources are also recorded and stored as a function of time. The stored information defining the intensity of the collected reflected light is analyzed by one or more computer processors utilizing special algorithms to produce a image of the object.

摘要： A super-resolution telescope. A target is illuminated with at least three laser beams, each beam having a slightly different frequency so as to produce an illumination pattern comprised of several sets of straight interference fringes which sweep across the target. The frequencies of the illumination beams are chosen so that each pair of beams has a unique beat frequency, and the corresponding fringe pattern for each pair sweeps over the target at a unique speed. By collecting a series of images, and demodulating them at the various beat frequencies, the downshifted spatial frequencies can be identified, correctly up-shifted, and fitted together with a set of special Fourier transform based algorithms to reconstruct high-resolution images. Applicants have performed laboratory experiments that this invention can provide resolution substantially better than diffraction limited resolution.

摘要： Embodiments of the invention pertain to a method for producing a spectacle lens with optimal correction across the entire lens taking into account the patient's complete measured wavefront. Specific embodiments can also take into account one or more additional factors such as vertex distance, SEG height, pantoscopic tilt, and use conditions. The lens wavefront can be achieved by optimizing a corrected wavefront, where the corrected wavefront is the combined effect of the patient's measured wavefront and the lens wavefront. The optimization of the corrected wavefront can involve representing the measured wavefront and the lens wavefront on a grid. In an embodiment, the grid can lie in a plane. During the optimization, a subset of the grid can be used for the representation of the measured wavefront at a point on the grid so as to take into account the portions of the measured wavefront that contribute to the corrected wavefront at that point on the grid.

摘要： An optical cross connect switch. In this switch any optical fiber in an input set of optical fibers, each carrying a communication beam, can be cross connected to any optical fiber in an output set of optical fibers. An alignment beam is added to and aligned co-axially with the communication beam carried by each fiber in the input set of optical fibers to define a communication-alignment beam for each fiber. Each communication-alignment beam is directed within a confined optical pathway to a specific exit aperture in an input array structure. The exit apertures for all of the communication-alignment beams are arranged in a pattern defining an input array so that each communication-alignment beam can be identified by the location of its exit aperture in the input array structure. Each communication-alignment beam is formed into a cross-connection beam by a micro-lens in a first lens micro-lens array. Each cross-connection beam is directed to a lens in a second lens array by two mirrors, a first mirror in a first mirror array and a second mirror in a second mirror array. The lens in the second micro-lens array focuses the communication beams into a specific input aperture of a confined optical pathway, preferably an optical fiber, in an output array structure. Each of the confined optical pathways in the output array structure is optically connected to an optical fiber of an output set of optical fibers. A first detector array located near the second lens array monitors the position of each alignment beam and provides position information to a processor for control of the mirrors in at least one of the mirror arrays.

摘要： An optical cross connect switch having a beam generating, beam directing, and beam receiving portions is disclosed. In one embodiment, the beam generating portion receives a number of optical fibers and generates a communication and companion alignment beam for each fiber. The communication and alignment beams may be spatially separated, substantially collimated beams, and are aligned to propagate away from the beam generating portion in substantially parallel paths. The communication and alignment beams then strike a beam directing element where they may be redirected to the beam receiving portion. A beam receiving portion includes a plurality of optical output fibers, each having an associated position sensor. The location where the alignment beam strikes the position sensor provides position information regarding the corresponding communication beam. Using the position information, the beam directing elements may be finely adjusted to direct the focused communication beam onto an optical output fiber.
