Appl. No.:

09/708469

Inventors:

Robert T. Carlson - Downington PA, US
Jesse W. Booker - Schwenksville PA, US

David Driscoll - West Chester PA, US

Assignee:

LSA, Inc. - Arlington VA

International Classification:

H04B010/24

US Classification:

398118, 398121, 398130

Abstract:

A wireless atmospheric site-to-site full-duplex (i. e. , simultaneous transmit and receive) laser communication system, typically for wideband (high-speed) data, voice, and/or video transmission. The system includes at least one laser communication transceiver each having an electro-optical transmitter that includes a laser source for generating laser light to be transmitted site-to-site and at high speed, an electro-optical receiver that includes a baffle assembly for receiving light directly onto a detector, without an intermediate field stop and re-imaging relay optics to reject off-axis light sources. Wideband data are transmitted and received through the atmosphere by the electro-optical transmitter and the electro-optical receiver. The data to be transmitted through each laser communication transceiver is inputted through a fiber-optic receiver and outputted by a fiber-optic transmitter. Outgoing laser light is generated by the laser source after it is triggered by an inputted signal from the fiber-optic receiver.

US Classification:

434 38, 434 69, 345 7, 348586, 356145

Abstract:

A periscopic optical training system for displaying simulation and real images includes a microprocessor for generating at least one simulation image, at least one display for displaying the simulation image, at least one periscopic device each with a viewing window for receiving the simulation and real images, and a controller for controlling the simulation and real images to be received by the periscopic device interchangeably or simultaneously.

Assignee:

LSA, Inc. - Arlington VA

International Classification:

G01B 11/24

US Classification:

356603, 356605

Abstract:

A Moiré deflectometer includes at least three non-mechanical, transparent, spatial light modulators for demonstrating two sets of patterns on two parallel planes on two of the modulators thereby creating a Moiré fringe pattern and a method for using the same. More particularly, each of the spatial light modulators may be a liquid crystal display, an electrochromic device, a micromirror array, a microlouvre array, an electro-optic device, or a holographic device.
