  • Publication number: 20190242676
    Abstract: An optical system for providing crosswind aim point correction for a sniper rifles and similar weapons comprising an optical transmitter, an optical receiver, a display device and a processor. The optical transmitter produces a collimated laser beam for illuminating a spot on the target. The optical receiver receives optical signals transmitted by the optical transmitter and scattered back from the target and converts the optical signals into time varying electrical signals. The processor processes the time varying electrical signals to determine a path weighted average crosswind. The processor is equipped with software that permits it to calculate the path-weighted average crosswind utilizing at least three different methods.

  • Publication number: 20170285343
    Abstract: A head worn display system with at least one retinal display unit having a curved reflector positioned in front of one eye or both eyes of a wearer. The unit includes a first set of three modulated visible-light lasers co-aligned and adapted to provide a foveal laser beam with selectable color and a first scanner unit providing both horizontal and vertical scanning of the laser beam across a small portion of the curved reflector in directions so as to produce a reflection of the color laser beam through the pupil of the eye onto a portion of the retina large enough to encompass the fovea.

  • Patent number: 9696161
    Abstract: A celestial compass kit. The kit includes an inclinometer, a camera system with a special telecentric fisheye lens for imaging at least one celestial object and a processor programmed with a celestial catalog providing known positions at specific times of at least one celestial object and algorithms for automatically calculating target direction information based on the inclination of the system as measured by the inclinometer and the known positions of at least one celestial object as provided by the celestial catalog and as imaged by the camera. The telecentric fisheye lens produces an image on the sensor located at or near the focal plane which remains spatially constant within sub-micron accuracies despite thermally produced changes in the focus of the lens.

  • Patent number: 8025425
    Abstract: An improved beaconless adaptive optics system and process. A target is illuminated with a high energy laser beam of a directed energy laser. Wave front measurements are made of high energy laser beam reflections from the target. These wave front measurements are analyzed by a high speed processor to determine both high frequency phase components and low frequency phase components in the wave front data. (Applicants' experiments have shown that there is a direct correlation between beam spot size on the target and the phase variance of the reflected laser beam. The correlation is: the greater the phase variance the smaller the beam spot size.) Applicants have developed a technique for providing special control algorithms that provide very high speed control of the elements of a deformable mirror using this phase variance as a feedback parameter. Applicants have also developed algorithms to correct a limited number of Zernike modes associated with the wave front control.

  • Publication number: 20110169953
    Abstract: A system and process for converting a series of short-exposure, small-FOV zoom images to pristine, high-resolution images, of a face, license plate, or other targets of interest, within a fraction of a second. The invention takes advantage or the fact that some regions in a telescope field of view can be super-resolved; that is, features will appear in random regions which have resolution better than the diffraction limit of the telescope. This effect arises because the turbulent layer in the near-field of the object can act as a lens, focusing rays ordinarily outside the diffraction-limited cone into the distorted image. The physical effect often appears as magnified sub-regions of the image, as if one had held up a magnifying glass to a portion of the image. Applicants have experimentally shown these effects on short-range anisoplanatic imagery, along a horizontal path over the desert. In addition, they have developed powerful parallel processing software to overcome the warping and produce sharp images.

  • Publication number: 20090177398
    Abstract: An angles only aircraft navigation system. The system includes an IMU coupled with a passive optical sensor. The optical sensor provides periodic updates to the IMU in order to correct for accelerometer and gyro drifts. The IMU computes the air vehicle's instantaneous position, velocity, and attitude using gyro and accelerometer measurements. The optical sensor images stars and satellites. The navigation filter combines optical sensor measurements with IMU inputs, and determines those corrections needed to compensate for the IMU drifts. By applying periodic corrections to the IMU using satellite angular measurements, the navigation filter maintains an accurate position estimate during an entire flight.

  • Patent number: 7447591
    Abstract: An automatic celestial navigation system for navigating both night and day by observation of K-band or H-band infrared light from multiple stars. One or more telescopes mounted on a movable platform such as a ship or airplane and directed at a substantially different portion of sky. Telescope optics focus (on to a pixel array of a sensor) H-band or K-band light from one or more stars in multiple telescopic fields of view. Each system also includes a GPS sensor and a computer processor having access to catalogued infrared star charts. The processor for each system is programmed with special algorithms to use image data from the infrared sensors, position and timing information from the GPS sensor, and the catalogued star charts information to determine orientation (attitude) of the platform.

  • Patent number: 7349804
    Abstract: An automatic celestial navigation system for navigating both night and day by observation of K-band or H-band infrared light from multiple stars. In a first set of preferred embodiments three relatively large aperture telescopes are rigidly mounted on a movable platform such as a ship or airplane with each telescope being directed at a substantially different portion of sky. Embodiments in this first set tend to be relatively large and heavy, such as about one cubic meter and about 60 pounds. In a second set of preferred embodiments one or more smaller aperture telescopes are pivotably mounted on a movable platform such as a ship, airplane or missile so that the telescope or telescopes can be pivoted to point toward specific regions of the sky. Embodiments of this second set are mechanically more complicated than those of the first set, but are much smaller and lighter and are especially useful for guidance of aircraft and missiles.
