Abstract: A method for optical digital signal processing, comprises configuring a plurality of binary mirrors to allow a subset of the binary mirrors to represent a range of values. The plurality of binary mirrors comprise a digital micromirror device. Light from a light source is received at the digital micromirror device. The intensity of the light is altered to represent one of the values based, at least in part, on the configuration of the subset of the binary mirrors. The altered light is transmitted from the digital micromirror device to a detector array.

Abstract: A processor such as a digital signal processor (DSP) is used to dynamically generate patterns and/or sequences of patterns for a spatial light modulator (SLM), such as a micromirror device, for the purpose of processing light. The combination of the processor and modulator has afforded optical signal processing in the digital domain and programmability that cannot be achieved with conventional analog optical computing.

Abstract: Optical wireless links communicate beam alignment information between them over a collimated, modulated light beam, without the requirement of a secondary channel. The alignment feedback signal can be formatted as control packets that are inserted between data packets traveling over the optical wireless channel, as control packets that are combined with the data packets, as a low frequency modulation of the light beam, or similar approaches. Alignment feedback signals are used by the device receiving the signal to align its light beam using a beam steering device, such as a micro-mirror device. Control signals preferably include x and y coordinate information relating to the position of both devices that are communicating, as well as time stamp, sample number, and similar synchronization information. Control packets are extracted from the data stream by a switch based upon the destination address of the control packets.

Abstract: A method and system for providing network configuration and control information. The configuration and control information is encoded and used to modulate the data-carrying optical signal. Later network elements demodulate and decode the data to determine configuration and control commands and requests. A method of providing network configuration data comprises receiving a data-carrying optical signal; providing control information; modulating the data-carrying optical signal using the control information such that the optical signal carries both the data and the control information; and transmitting the modulated optical signal. A spatial light modulator, typically a micromirror array, may be used to modulate the optical signal.

The computer system (100) has a storage (HDD, 110) holding an operating system (OS) and an application program (APP.exe), a first processor (106) having an instruction set, and a second processor (1730) having a different instruction set. The process includes steps of 1) running (2424) at least some of the operating system (OS) on the first processor (106) so that the first processor (106) sets up for at least part of the application program at run time at least one second processor object (VSP OBJECT 1); and 2) concurrently running the second processor (3310) to access the second processor object (VSP OBJECT1) and thereby determine operations for the second processor (1730) to access second processor instructions for said part of the application program (APP.exe) and data to be processed according to said second processor instructions, and running (2436) the second processor (1730) to process the data according to said second processor instructions.

Abstract: A process is provided for operating a computer system (100) having a storage holding an operating system (OS) and an application program (APP.exe) and a third program (VSP Kernel), a first processor (106) having an instruction set, and a second processor (1730) having a different instruction set. The process includes a first step of running the first processor (106) to determine whether a part of the application shall be run on the first processor or the second processor and then establishing a second processor object (VSP OBJECT1) if said part shall be run on the second processor and the first processor (106) sending a message that the second processor (1730) is to run said at least part of the application program. The third program establishes message handling functions and bus masters data transfer operations for the second processor between the host running the operating system and the second processor running the third program.
