Abstract: A celestial compass. The celestial compass includes a camera with a wide angle lens suitable for viewing a large portion of the sky and a many-pixel sensor for collecting images of celestial objects such as stars, planets, the moon and the sun. The compass also includes a computer programmed with an (1) astronomical algorithm for providing the precise position of celestial objects based on precise input of time (date and time of day) and observation position (latitude and longitude), (2) celestial navigation software and (3) coordinate transformation software to correct distortion, convert pixel image data to astronomical coordinates and determine the instruments azimuth. The system includes provisions for the input of precise time and location information.

Abstract: Diagnostic instruments, systems and methods for performing measurements on eyes are disclosed. In one embodiment of the instrument, a left ocular is disposed in a portion of a left visual path for the left eye, the left ocular positioned to permit the left eye to view a target, a right ocular is disposed in a portion of a right visual path for the right eye, the right ocular positioned to permit the right eye to view a target. The instrument can also include a wavefront sensor disposed on a translation stage, the wavefront sensor having an optical path to an imaging sensor, the translation stage being movable to position the optical path of the wavefront sensor in alignment with the portion of the left visual path in a first state and in alignment with the portion of the right visual path in a second state. One or more light sources are optionally provided for propagating light along a least part of the left and right visual paths to illuminate the left and right eyes.

Abstract: A large clear aperture cat's eye retro-reflector system that improves the optical efficiency by two orders of magnitude over conventional cat's eye retro-reflectors. It achieves this increase by using a wide-angle lens design with a curved focal plane, so the entrance aperture is not limited by the design constraints of a solid glass sphere. Since light reflected from a retro-reflector increases as the fourth power of the reflector aperture, light reflected from the retro-reflector of the present invention is increased by two orders of magnitude as compared to the prior art cat's eye retro-reflector of conventional size. When used as a communication device, the retro-reflector is preferably modulated by a quantum well modulator providing very high speed communication. In preferred embodiments a moving quantum well modulator is placed near the focal plane, where the beam footprint is much smaller than the entrance aperture, effectively allowing a small modulator to modulate a large diameter beam. A tracking system tracks the source of interrogating beams and positions the small modulator to intersect the incoming beam near the focal plane where the beam footprint is very small.
