US Patent:

51535971, Oct 6, 1992

Filed:

Dec 13, 1976

Appl. No.:

5/752713

Inventors:

Werner G. Hueber - China Lake CA
James L. Jernigan - Inyokern CA

International Classification:

G01S 7295

US Classification:

342192

Abstract:

An acousto-optical classifier for classifying wide bandwidth signals such as high resolution radar returns of ships or very short pulse length signals of radar emitters. This is accomplished by generating the Fourier transform power spectrum with an acousto-optic cell oriented in the Bragg configuration and a low power coherent light source such as a laser. The power spectrum is detected to provide inputs to a digital classifier.

International Classification:

G01B 1126
F41G 700
G01J 120

US Classification:

356152

Abstract:

An active (laser) and passive guidance system having a common sensor (siln-vidicon) for target acquisition, non-imaging seeker (four quadrant detector integrated with four single detectors, gyro optics, electronics), and aim-point correlator. In the passive mode, the pilot detects the target on the sensor's visual display; aligns the seeker with the target by aim-point correlation, and initiates seeker tracking. In the laser mode, the seeker acquires and tracks the target, the acquisition sensor scans the area, and its signals are correlated with the seeker four detector signals. The point of maximum correlation is indicated on the display of the acquisition seeker and shows the point of laser illumination and seeker tracking.

US Classification:

350 96BC

Abstract:

An image attenuator having an attenuation range of over 100,000. An optical ens device focuses the image on a first liquid crystal layer which scatters the directed light only when an electrical potential is applied to the crystal layer by means of transparent electrodes, and in proportion to the strength of potential applied. A proportion of the scattered light is absorbed within a coherent fiber optic layer, the thickness and the spacing of the individual fibers of which can be varied to vary the contrast and attenuation of the system. Several stages may be stacked in series to obtain a greater degree of attenuation.
