International Classification:

H01J 150

US Classification:

313161

Abstract:

The present invention provides an arc lamp for producing a high intensity point source of light by magnetically compressing the light emitting element of the arc lamp. Arc lamp point light source 30 includes bulb 32 having two electrode 34, 36 spaced apart to have gap 35 therebetween and hermetically sealed within bulb envelope 44 filled with ionizing gas. Connector 46 is provided for applying a voltage potential across electrodes 34, 36 causing electric current to pass therebetween to generate arc plasma 42. Annular magnet 48 and bar magnet 50 located outboard of bulb envelope 44 generate a magnetic field around arc plasma 42 to compress the volume thereof between electrodes 34, 36.

International Classification:

G03B 2114

US Classification:

353 88

Abstract:

A volumetric display system includes a display member which has a plurality of electrically-responsive optical shutters arranged in a layered relationship. The optical shutters include layers of a liquid crystal which preferably can be formed in geometric shapes which enhance the volumetric display. A projection system projects successive images onto the display member while successive ones of the optical shutters are switched into their translucent state. At any moment in time, all optical shutters except the successive one are maintained in a transparent state.

Abstract:

A modular enclosure system particularly suited for use aboard a ship comprises a modular enclosure which is easily installed into and removed from an exoskeletal frame that is shock-mounted to a fixed surface, such as the deck of a ship. An enclosure is installed by placing it within a respective frame via complementary guide rails. A securing mechanism locks the enclosure into place within the frame, and an ejection mechanism enables an enclosure to be easily removed for purposes of maintenance, repair or reconfiguration, or in the event of an emergency. The enclosures are preferably water-tight and float if ejected into the sea. Rubberized boots surrounding all points of entry enhance the survivability of the enclosures in a nuclear/biological/chemical (NBC) environment. Shock-mounting the frames to the deck eliminates the need to shock-mount individual pieces of equipment and enables the use of cheaper and more readily available commercial off-the-shelf equipment. A number of frames and enclosures can be placed side by side on the deck of a ship to form a superstructure.

International Classification:

G02B 2722

US Classification:

359462

Abstract:

An autostereoscopic display includes a projection system which generates a plurality of real images that represent different spatial views of an object and further includes a plurality of contiguous field lenses. From the real images, the field lenses form a plurality of exit pupils which are separated by one interpupillary distance. An observer can "walk around" the display and observe different stereoscopic views of the object by positioning his eyes at an adjacent pair of exit pupils.

International Classification:

G02F 11335
G02F 11343

US Classification:

359 40

Abstract:

A polarizing beamsplitter (PBS) that can be used with reflective light valve displays includes two polarizing surfaces. A light source projects opposing readout beams onto the polarizing surfaces, which reflect linearly polarized (S or P) components of the readout beams. The polarized readout beams illuminate respective portions of a reflective light valve cell that bears an image intensity pattern. The cell spatially modulates the readout beams' polarization in accordance with the image intensity pattern and reflects the polarization modulated beam back towards the polarizing beamsplitter. The PBS spatially analyzes the readout beams' intensities in accordance with their polarization modulations.

Abstract:

A solid state aperture is formed with an optical system and an electrode system. In different embodiments, the optical system includes electrically-responsive attenuation members, e. g. , black guest host liquid crystals, and electrically-responsive, polarization-rotation members, e. g. , twisted nematic liquid crystals. The electrode system includes electrodes of electrically conductive, optically transparent materials which are applied to the optical system to define attenuation segments of a desired attenuation pattern.

International Classification:

G03B 2100

US Classification:

359 40

Abstract:

Optical apparatus that condenses illuminating light into a narrow formatted band of light that follows activated lines down a light valve as it is driven. The present invention is a telecentric illumination scanning system that comprises an input lens group, a rotatable or oscillating reflective scanner, an output lens group and a polarizing element. The input lens group transmits light provided by a light source to the scanner, which is reflected therefrom and is directed to the output lens group. The light transmitted by the output lens group is polarized by the polarizing element and applied to the light valve. The input and output lens groups focus the light provided by the light source into a relatively narrow band of light that is scanned by the rotatable or oscillating scanner across the face of the light valve. A telecentric light zone is formed in a predetermined space between the output lens group and the light valve. Scanning is accomplished by varying the angle of the bundle of chief rays at the aperture stop.

Abstract:

A full color 3D projection display using wavelength separation which, through a combination of retarders, prisms and dichroic and polarizing coatings, takes linearly polarized red and green light of p orientation from left and right images and blue linearly polarized light of p orientation from one of the views or a common image, and presents the light for projection having green and red light of one polarization orientation for one view and red and green light of a polarization with another orientation for providing the 3D components of the image. The blue light component is presented alternately in one of both polarization orientations to be perceived with the left and right views, respectively.
