Internally Cooled Large Aperture Microlens Array With Monolithically Integrated Microscanner
US Patent:
5420720, May 30, 1995
Filed:
Jan 29, 1993
Appl. No.:
8/011323
Inventors:
George Gal - Palo Alto CA
Howard E. Morrow - San Jose CA
Howard E. Morrow - San Jose CA
Assignee:
Lockheed Missiles & Space Company, Inc. - Sunnyvale CA
International Classification:
G02B 2710
G02B 2300
G02B 2300
US Classification:
359622
Abstract:
A large aperture microlens array assembly has at least two arrays of microlenses with individual unit cell trains optically interconnecting individual microlenses in one array with related individual microlenses in another array. In each unit cell train the light entering an entrance pupil of a microlens in one array is transmitted through the exit surface of a related microlens of the other array to provide a collimated output through the exit. One array may be moved with respect to the other array for scanning a field of regard.
Wavefront Corrector For Scanning Microlens Arrays
US Patent:
5450241, Sep 12, 1995
Filed:
Jul 7, 1994
Appl. No.:
8/271499
Inventors:
George Gal - Palo Alto CA
William W. Anderson - Half Moon Bay CA
Bruce J. Herman - Mountain View CA
Dean M. Shough - Newark CA
William W. Anderson - Half Moon Bay CA
Bruce J. Herman - Mountain View CA
Dean M. Shough - Newark CA
Assignee:
Lockheed Missiles & Space Co., Inc. - Sunnyvale CA
International Classification:
G02B 2710
US Classification:
359619
Abstract:
Wavefront correction apparatus for correcting a stepped wavefront output produced by certain angles of scan and by certain positions of scan in scanning microlens arrays includes anamorphic transfer optics with diffractive corrections. The transfer optics form the outputs of all of the unit cell trains of the microlens arrays into a unique, separate, linear image at each position of scan of the scanning array. A stepped wavefront corrector is positioned in the path of each linear image, and selected thicknesses of the material in the stepped wavefront corrector are effective to vary the times of optical passage through the stepped wavefront corrector in amounts to restore the wavefront to a continuous, unstepped form at the outlet of the plate.
Method For Fabricating Microlenses
US Patent:
5310623, May 10, 1994
Filed:
Nov 27, 1992
Appl. No.:
7/982514
Inventors:
George Gal - Palo Alto CA
Assignee:
Lockheed Missiles & Space Company, Inc. - Sunnyvale CA
International Classification:
G03C 500
US Classification:
430321
Abstract:
A microlens of any designed configuration is formed as a replica in a photoresist material, and the photoresist material replica is used to reproduce the replica directly in a substrate material.
Exposure Mask For Fabricating Microlenses

Inventors:
George Gal - Palo Alto CA
Assignee:
Lockheed Missiles & Space Company, Inc. - Sunnyvale CA
International Classification:
G03F 114
US Classification:
430 5
Abstract:
A microlens of any designed configuration is formed as a replica in a photoresist material, and the photoresist material replica is used to reproduce the replica directly in a substrate material.
Laser Velocimeter
US Patent:
4859055, Aug 22, 1989
Filed:
May 17, 1988
Appl. No.:
7/194781
Inventors:
George Gal - Palo Alto CA
Howard E. Morrow - San Jose CA
Howard E. Morrow - San Jose CA
Assignee:
Lockheed Missiles & Space Company, Inc. - Sunnyvale CA
International Classification:
G01P 336
G01P 522
G02B 900
G01P 522
G02B 900
US Classification:
356 28
Abstract:
An aircraft velocimeter comprises means for projecting three pairs of independently generated ribbon-shaped laser beams to a measurement volume located at a predetermined distance from the aircraft with a predetermined separation being maintained between the two ribbon-shaped laser beams of each pair at the measurement volume. The times of flight of atmospheric aerosol particles between the two ribbon-shaped laser beams of corresponding pairs of laser beams are measured as the aerosol particles pass through the measurement volume. From the predetermined distance between the two ribbon-shaped laser beams of each pair and the measured time of flight of an aerosol particle across that predetermined distance, a component of velocity of the aerosol particle relative to the aircraft is calculated for each pair of ribbon-shaped laser beams. From the three components of velocity corresponding to the three pairs of ribbon-shaped laser beams projected to the measurement volume, a vector measurement of the velocity of the aircraft relative to atmospheric particles in the surrounding atmosphere is obtained using an on-board computer programmed with a conventional algorithm.

Color Separation Microlens
US Patent:
5600486, Feb 4, 1997
Filed:
Jan 30, 1995
Appl. No.:
8/380109
Inventors:
George Gal - Palo Alto CA
Bruce J. Herman - Mountain View CA
Bruce J. Herman - Mountain View CA
Assignee:
Lockheed Missiles and Space Company, Inc. - Sunnyvale CA
International Classification:
G02B 518
G02B 2742
G02B 2710
G02B 2742
G02B 2710
US Classification:
359569
Abstract:
A color separation microlens is fabricated to be a single micro-optical element made up of a color separation grating integrated with a refractive lens. The color separation microlens separates the spectrum into distinct color spots and focuses these spots to a common plane. The spots fall at the locations of the different diffraction orders of the grating. The color separation is done by the grating, and the focusing is done by the lens. The color separation microlens can be fabricated as a monolithically integrated element (an element in which the grating and the lens are combined to a single surface) and can also be fabricated as a dual-sided thin wafer (a wafer in which the grating is on one side and the lens is on the other).
