Assignee:

Cubic Corporation - San Diego CA

International Classification:

H04B 10/00

US Classification:

398170, 398169, 398118

Abstract:

A system, method, and communication device are disclosed. The system can include an optical interrogator and a phase-modulating communication device. The communication device can include a retro-optimized lens, a phase modulator, and a processor. The retro-optimized lens can be a non-imaging optical arrangement configured to minimize deviation between an incoming signal and a reflected signal used for return link communications. The processor can be configured to calibrate a modulation path length of the communication device based on a wavelength of the communication signal and can control an operation of the phase-modulator to send phase-coded messages to the interrogator. Optionally, the processor can perform a real-time phase calibration of the communication device using feedback from the interrogator.

Abstract:

An eye detection system, method, and apparatus are disclosed. The eye detection apparatus includes illuminator, receiver, processor, and memory elements. The illuminator emits radiation at predetermined wavelengths from the eye detection apparatus toward an area of interest. Radiation from the area of interest is detected at the receiver which, in turn, provides sensor data to the processor. The processor is coupled to the illuminator and receiver and controls their respective operations. The processor detects a pattern representative of a human eye in the sensor data and determines coordinates of an object corresponding to the pattern. The memory stores the coordinates of the object. Optionally, the eye detection apparatus communicates the coordinates of the object to a wireless device and directs countermeasures to the object's coordinates in response to commands from the wireless device.

US Classification:

398115, 398202, 398135

Abstract:

A system, method, and optical communication device are disclosed. The system can include a plurality of optically coupled nodes forming an optical communication network. Each node may include an array of pixel elements, each pixel element having an optical detector and an active optical source. The pixel array may be disposed in a backplane of a lens that is configured to map incoming optical signals to pixel locations in the backplane according to their respective angles of incidence and to minimize a deviation at each pixel location between incoming optical signals arriving at the optical detector and emissions from the optical source. The node may include a processor and memory. The processor can register senders in the optical network at locations in the pixel array and can generate routing information by which to route communications from the registered senders to other pixel elements for transmission to their respective destinations.

International Classification:

H04B 1000

US Classification:

359152

Abstract:

A laser communication transceiver for transmitting information via laser beams to and from other similar laser communication transceivers. Each transceiver comprises a wavelength locked beacon laser providing a beacon beam. The transceivers determine the precise location of other transceivers by detecting these beacon beams with beacon receive units comprising atomic line filters matched to the beacon wavelength. Signals are transmitted by imposing an electronic signal on laser beams produced by one or more signal laser devices. These signals are directed with precision at other transceivers, and the signal beams are detected with very narrow field of view signal receive units. In a preferred embodiment, these transceivers are installed on 66 satellites in low earth orbit and on selected mountain tops on earth to provide a global communication system.
