US Patent:

7245800, Jul 17, 2007

Filed:

Sep 8, 2004

Appl. No.:

10/936463

Inventors:

Brian L. Uhlhorn - Eagan MN, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G02B 6/28

US Classification:

385 24, 385 15

Abstract:

An optical transmission system for transmitting optical data comprises an optical transmitter, an optical receiver and a transmission medium capable of providing a visual indication of transmission status as well as the location of potential faults within the transmission medium. The optical transmitter supplies a first nonvisible light source for transmitting optical data and a second visible light source providing a visual indication of transmitter operation and possible faults. The first nonvisible light source and the second visible light source are transmitted across the transmission medium whereby they are received by the optical receiver. The optical receiver includes a filter member for removing the visible light source prior to converting the second visible light source into an electrical signal.

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G09G 5/00

US Classification:

345 8

Abstract:

A direct ocular virtual 3D workspace (laser-based 3D display system) utilizes traditional binocular methods of image composition to produce a 3D workspace in the observers' psyche. This direct ocular virtual 3D workspace is implemented such that in moving environments, such as on a ship or vehicle, the immersion of the individual into the display environment will not result in vertigo and/or motion sickness. This is resolved by utilizing a system that accomplishes eye-tracking, and produces the display image within the eye by means of laser projection. Two images can thus be projected into an individual's eyes to produce a 3D holographic-like image space. The individual will still maintain partial vision, resulting in a holographic-like display in space that the observer can look through. The images provided to multiple collaborators/users are geometrically corrected for each collaborator.

US Classification:

398 2, 398 1, 398 3, 398 4, 370225, 370223, 370222, 370228

Abstract:

Apparatuses, systems, and methods of routing data through an optical network are disclosed. One such method includes transmitting optical data via a first fiber optic network from an originating node on a first level to a second level, receiving the optical data at a destination node on a third level from the second level via a second fiber optic network, wherein the second level, connected to the first fiber optic network and the second fiber optic network, includes a first intermediate node as a primary route on the second level for transmitting the optical data from the originating node to the destination node, and a second intermediate node as an alternate route on the second level for transmitting the optical data from the originating node to the destination node when the first intermediate node fails.

International Classification:

G02B 6/12

US Classification:

385014000, 385037000

Abstract:

The present disclosure is directed to an optical apparatus suitable for coupling to an optical network. The optical apparatus is adapted to transmit multiplexed optical signals on the optical network and/or de-multiplex optical transmissions from the network. The optical apparatus includes an optical waveguide and an optoelectronic device. The optical waveguide has a set of diffractive elements in the form of a scribed volume hologram, which provides an optical transfer function. The optical waveguide also includes a first optical port and a second optical port. The second optical port is adapted to be optically coupled to the optical network. The optoelectronic device includes a plurality of optical portions. The optoelectronic device is adapted to convert optical signals at the optical portions into electric signals and/or convert electric signals into optical signals at the optical portions.
