Appl. No.:

09/962629

Dale L. Hook - Rancho Palos Verdes CA
Josef Shwartz - Beverly Hills CA
Jeffery L. Sollee - El Segundo CA

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

H01S 3223

US Classification:

372 55, 372 89, 372109

Abstract:

A laser weapon system using a high energy deuterium fluoride (DF) or hydrogen fluoride (HF) laser, for which all necessary reactants and other materials are carried on an easily movable vehicle. Reactant gases are stored mixed with a diluent gas, such as helium, for ease of handling and to provide nearly ideal gas behavior. Cooling water for the laser is also employed in a high pressure steam generator that uses diesel fuel and oxygen to produce heat. Apart from a fluorine generator, the system uses only four storage tanks for reactant gases.

International Classification:

H04B 10/06

US Classification:

398212, 398202

Abstract:

A receiver chip, system and method for on-chip multi-node visible light communication, the receiver chip comprising: an array of receiver cells comprising an array of photodetectors, each receiver cell comprises at least one photodetector and is to receive light through the at least one photodetector, and a logical layer for independently configuring at least one selected receiver cell as a communication receiving channel. The system comprises an array of receiver cells comprising an array of photodetectors, each receiver cell includes at least one photodetector and is to receive light through the at least one photodetector, a logical layer to independently configure at least one selected receiver cell as a communication receiving channel, and a processor to receive data from the logical layer and control the logical layer for configuration of the receiver cells.

International Classification:

B64O 104

US Classification:

89 111

Abstract:

A laser weapon system and method are provided for detecting and engaging a large number of target munitions with a plurality of independently steered laser beams, and is particularly adapted to defend against multiple biological and chemical warfare munitions. The system includes a laser generator for generating laser energy and a segmented mirror having an array of controllable mirror segments for dividing the laser energy into a plurality of steerable laser beams. The low energy divided laser beams are directed through an amplifier to achieve high energy laser beams which are output in a fanned array within a shield zone. A detector senses the presence of munitions. An illuminator laser continually sweeps the shield zone and a receiver receives reflections from munitions which fall within the shield zone. The relative position of the detected munitions within the shield zone are compared to the position of laser beams and control signals are determined so as to steer the laser beams to engage the detected munitions within the shield zone and attempt to destroy the engaged munitions.
