Publication number: 20090162071Abstract: Free-space optics (FSO) is an unlicensed line-of-sight technology that uses modulated optical lasers to transmit information through the atmosphere. By using invisible beams of light, FSO can transmit and receive voice, video, and data information. To date, the primary concentration of FSO research and development has been toward the accurate alignment between two transceivers. The invention (FSO system) provides viable optical beam steering and capturing mechanism to allow fast tracking and accurate pointing between two transceivers of free-space optic (FSO) link that required continuous alignment. This extra ordinary auto-tracking system can reduce the time needed to lock a laser beam between an aircraft and a stationery base station to exchange information in addition to its high accuracy. This invention also provides wider receiving angle compared with the conventional FSO system.Type: ApplicationFiled: December 19, 2007Publication date: June 25, 2009Inventors: Hakki H. Refai, James J. Sluss, JR.
