Filed:

Jan 31, 1996

Appl. No.:

8/594159

Inventors:

Ning Wu - Rancho Palos Verdes CA

International Classification:

A42B 300

US Classification:

345 8

Abstract:

A visual display and helmet assembly is configured to function in the presence of a harsh environment, e. g. , high wind, vibration and shock and strong ambient light. The visual display preferably includes a transmissive liquid-crystal display to reduce the display's size and to enhance the intensity of a virtual image. In addition, the display is preferably reconfigurable so that different display indicia can be programmed as desired. To reduce probability of injury to a user, the visual display is carried on the exterior of the helmet with its center of mass positioned substantially on the midsagittal plane of the user. In addition, a mount permits the visual display to detach from the helmet when it is subjected to forces above a predetermined threshold. The mount is also permits yielding movement between the visual display and the helmet to enhance viewing of the image.

Appl. No.:

8/455864

Inventors:

Ning Wu - Rancho Palos Verdes CA
Jerome R. Laskowski - Newbury Park CA

Assignee:

Delco Electronics Corporation - Kokomo IN

International Classification:

G02B 2714

US Classification:

359630

Abstract:

The image source of a head up display for a motor vehicle is illuminated from a remote high intensity source using fiber optics. The HUD image source and optics are under the dash pad of the vehicle and include color LCD or color filtered image source. The image is lighted by a high intensity light source which yields a bright projected image and which generates substantial heat. The light source includes lamps in a fan-cooled heat sink located in the vehicle engine compartment, for example, and coupled to the image source by fiber optic light guides. The light guides abut the image source to uniformly light small image patterns commensurate with the light guide size, or light spreading techniques are used for larger image patterns.

US Patent:

Filed:

Dec 19, 1984

Appl. No.:

6/683783

Inventors:

Ning Wu - Rancho Palos Verdes CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

G01B 902

US Classification:

356353

Abstract:

An improved method and apparatus for measuring the aberrated wave slope of an optical beam. The apparatus includes a shearing interferometer having a reference mirror 14 and a steerable mirror 16 mounted perpendicularly to one another with a beam splitter 10 disposed at a 45. degree. angle to each. The beam splitter 10 directs a portion of the incident beam to the reference mirror to form a reference beam 20 and transmits a portion 22 of the incident beam to the steerable mirror. The steerable mirror 16 is pivoted about two mutually perpendicular axes to form a shearing interference pattern at a detector array 24 when a portion of the incident beam is reflected off the steerable mirror 16 and combines with the reference beam 20 reflected off the reference mirror. The reference mirror 14 is periodically displaced to modulate the reference beam 20. In operation, the steerable mirror 16 is first oriented pivotally about a first axis perpendicular to the propagation axis of the incident beam to a pre-selected angle and the reference mirror is then periodically displaced.

International Classification:

G03B 300

US Classification:

364525

Abstract:

A complex optical system may be maintained in alignment by means of a technique in which an analytical model of the system is utilized which is assumed to be capable of essentially optimal performance. A physical example of the same system design is then assembled and a plurality of performance characteristics are measured related to the intensity function associated with a point source image on the system's focal plane detector array. A plurality of specific adjustments are then calculated by means of a second order approximation technique which would have the effect of degrading the performance of the analytical model to equal that measured for the physical example, whereupon compensating physical adjustments are made to the physical example to improve its measured performance.
