The present invention provides a device is provided for use with a first through fourth light beams. The device includes a first through fourth waveguides and first through fourth light scattering portions. The first waveguide has a length and a width and is arranged to receive the first light beam, wherein the length is larger than the width. The second waveguide is parallel with the first waveguide and is arranged to receive the second light beam. The third waveguide is disposed perpendicularly to and intersecting with the first waveguide and the second waveguide. The third waveguide is arranged to receive the third light beam. The fourth waveguide is parallel with the third waveguide and is disposed perpendicularly to and intersecting with the first waveguide and the second waveguide. The fourth waveguide is arranged to receive the fourth light beam. The first light scattering portion is disposed at the intersection of the first waveguide and the third waveguide. The second light scattering portion is disposed at the intersection of the second waveguide and the third waveguide. The third light scattering portion is disposed at the intersection of the first waveguide and the fourth waveguide. The fourth light scattering portion is disposed at the intersection of the second waveguide and the fourth waveguide. The light scattering portions can scatter light normal to the waveguides.

System and method for using planar device to generate and steer light beam

A communications system for wireless transceiving of information, comprising at least one multiple optical beam scanning array transceiver located in a satellite for wirelessly transceiving the information; and at least two terminals at diverse locations capable of wirelessly transceiving the information between the terminals and the satellite, and an apparatus for determining atmospheric conditions for use in adjusting the multiple beam scanning array transceiver parameters.

Mobile communications via an optical signal during adverse atmospheric conditions

A system and method for providing real-time imaging for use in wide area space based surveillance utilizing an Optical Tera-bps Satellite (OPTSAT) network, including a plurality of OPTSATs, wherein an object is imaged with at least one surveillance aperture operatively linked to at least one of the plurality of OPTSATs is disclosed herein. The optical image data obtained the at least one surveillance aperture is processed in a one image processor, and displayed in a terminal capable of wirelessly transceiving information with the plurality of OPTSATs.
