  • Patent number: 6072524
    Abstract: This invention relates to an apparatus for observing objects and determining their position. A SIRPS (Staring Infrared Panoramic Sensor) for observing objects in a 360.degree. field of view around the SIRPS is coupled with a GPS (global positioning system) to give position data for the objects observed by the SIRPS, an IMU (inertial measurement unit) which provides data on the attitude of the SIRPS and a transmitter to transmit the view of the objects and the position data to a user having a display showing him the objects and positions of the objects. The SIRPS, IMU, GPS and transmitter/receiver are combined in a pod which is placed in a position where it can have a large field of view such as by being flown over the area to be observed such as under a modified Rogollo wing tethered to the ground to hold it in position. A repeater will allow two way communications through the device which is in the air such that radio communications over barriers, such as hills, is enabled.

  • Patent number: 5883713
    Abstract: A Fourier transform interferometer for rapid scanning of scenes such as explosions wherein an incoming beam of light to be analyzed is split by a beam splitter into a first portion and a second portion. The first portion of the incoming light is sent down one arm of the interferometer where it passes through a rotating scanning cube for changing the path length in that arm of the interferometer. The light is then reflected by a retro mirror and sent back through the scanning cube to the beam splitter for sending a portion of the returning beam to a detector. The second portion of the incoming light is sent down a second arm of the interferometer where it passes through a compensator. The light is then reflected by a retro mirror and sent back through the compensator to the beam splitter for sending a portion of the returning beam to a detector. The first and second portions of the incoming light having differing path lengths interfere and the detector measures the fringes created.

  • Patent number: 5841589
    Abstract: An optics assembly for observing a panoramic scene comprises a plurality of optical elements. A flat reflective element redirects light from a panoramic scene. A plurality of refractive elements, successively receive the redirected light from the reflective element and create a real pupil. An optical relay system receives light from a last of the plurality of refractive elements. The optical relay system establishes the focal length of the optics assembly, corrects optical aberrations produced at the real pupil, corrects field aberrations and produces an annular image on a flat focal plane assembly. The optics assembly produces a small F-number at field angles perpendicular to the optical axis of the optics assembly over a panoramic scene.

  • Patent number: 5627675
    Abstract: An optics assembly for observing a panoramic scene. The optics assembly includes a plurality of optical elements. A first element redirects light from the panoramic scene. The optical power of the first element forms an imaginary pupil. The energy from the first element is redirected about 90 degrees, forming an annular path. A second element receives the redirected light and re-images the imaginary pupil to form a real pupil. This portion of the energy continues to be in an annular form. A third element includes an optical relay system having a group of reimaging optics. The third element receives light from the second element while relaying the real pupil into the reimaging optics. It also establishes the focal length of the optics assembly, corrects pupil aberrations produced at the real pupil, corrects field aberrations and produces an annular image on a flat focal plane. The optical relay system interfaces with the second element through the use of the real pupil.

  • Patent number: 5502309
    Abstract: A staring sensor apparatus which includes an optics assembly for providing a panoramic field of view in which the field of view in one direction is considerably larger than the field of view in the direction perpendicular thereto. A two-dimensional focal plane assembly (FPA) collects and converts an incoming optical signal from the optics assembly to an electrical wave form which depicts the energy falling on each pixel of the FPA in a discrete unit of time. The resulting pixel outputs thus represent the energy emitted from specific calibratable around the optics assembly.
