With Movable Beam Deflector Or Focussing Means Patents (Class 250/347)
  • Patent number: 3971939
    Abstract: A combination of a wobble-scan infrared (IR) seeker with an unscanned pul laser (L) seeker. Target IR&L energy is passed through a focusing lens system to a wedge filter which is mounted on a rotating gyro-stabilized platform. The filter separates the IR&L signals by reflecting the L signal from its top surface and the IR signal from its bottom, slanted surface. The L signal is focused on a quad cell detector and detected. The IR signal passes through this detector and is sent through a reticle which pulse-codes it. The pulse-coded IR energy is then focused by another lens on an IR detector.

  • Patent number: 3963920
    Abstract: An integrated optical-to-electrical signal transducing system and apparatus therefor which, through the use of a novel combination of fiber optics and microelectronics, permits locating the optical signal detection circuits close to their associated preamplifier circuits and remote from sources of interfering signals without losing the ability to do effective optical tracking or seeking. Specific structure including a hybrid microelectronic device package modified to receive optical input signals through a fiber optics terminal incorporated therein is provided to achieve the desired results.

  • Patent number: 3946233
    Abstract: Weapons system for both detection and affecting of stationary or moving objects. A laser beam is generated at a relatively low power level and caused to monitor, as by sweeping, a predetermined zone or space. Said laser beam or a portion thereof is reflected by and from an object appearing within said zone or space and is sensed by suitable detection means. The detection means provides the input to a computer which then locks the generator onto said object and simultaneously increases the power emitted therefrom to a predetermined higher, as destructive, value. Friendly objects operating within the same area can be caused to emanate a signal beam which is sensed simultaneously with the sensing of the reflected laser beam and prevents the actuation of the computer.

  • Patent number: 3936629
    Abstract: A horizon sensor for satellites comprising a mask with four sets of four openings one of which receives a projected portion of the earth-space transition line, another is in the form of a grating and the remaining two slit-shaped openings include each a detector on which a secondary image of the grating or of the transition are reflected by an oscillating concave spherical mirror to derive therefrom a digitized measuring signal indicating the position of the transition line.

  • Patent number: 3934137
    Abstract: In an optical scanning device in which radiation beams from different zones of a field of view are consecutively converged onto a radiation sensitive detector, an optical projection system is included in the radiation path between an objective and an optical cylinder which is provided with optical convergence systems at its circumference. Said projection system conjugates the center of the objective and the center of rotation of the cylinder.
