Abstract
The invention advances a method of point-point tracking transmission of space wireless optical communication, mainly using optical WDM technique to transmit communication signal and simultaneously detect the power phase of incident light to generate and output corresponding signal power, regulating the 3D mobile machine seat of an optical signal transmitting (receiving) device to keep the incident light power in the optimum state, on the point-point moving condition, able to keep the transmission signal uninterrupted. It is applied to the wireless communication system in progress between vehicle (ship) as well as airplane and ground.
Description
The wireless space optical communication technique provides and need not any physical circuit (cable, optical cable) between points and connect, and capacity, speed can both meet the demands.As long as can keep between the opposite end in the certain distance scope and hypervelocity when catching the other side's signal source, can realize the transfer function between the interactive wireless light communication transmitting-receiving opposite end.
The present invention proposes and utilize lightwave signal detected signal when receiving that the direction that transmits and receives device is adjusted at any time, keep the accurate road butt joint that receives.Be applicable to car (ship) in advancing and the radio optical communication system between aircraft and the ground.Specify:
Fig. 1 is the wireless light communication schematic diagram under the normal condition
101 and 102 are used for the proper alignment operation of free-space optical communication system, optic communication device 103 light beams that produce, the Data Modulation of receiving in the modulated device 104 usefulness networks 110, and Emission on 106, receiving optical signals device 102 focuses on the friendship bundle of incident on 112, by 129 convert electric signal transmission to goes out the implementation space optic communication. In fact at the transmitting-receiving optical signal Similar 103 and 104 devices also are housed on 102, also fill at transmitting-receiving optical signal device 101 equally Signal transceiver 129 functions are arranged, so this system is beidirectional.
When between points distance, when direction changes, and other factors is when influencing, and light beam 203 has departed from the predetermined scope of transmitting-receiving optical signal device, just has the variation of a signal power phase place on transceiver, and derives and be detected.Because ray velocity is high, so the response of shifted signal is high, can pass through detector 201 continuous repeated measurement shifted signals.By output corresponding signal power, again by implementing three-dimensional polar coordinates adjustment by 202 pairs of transmitting-receivings of the three-dimensional support that moves light signal, till light signal is replied predetermined scope.
It is on the passage of space optical communication that wireless signal feedback between point-to-point has multiple methods, the present invention, utilizes wavelength division multiplexing (WDN) technology to realize signal transmission and feedback, and cooperation can be made the three-dimensional support of adjusting and form an automatic adjustment system.Provided by the present invention is a kind of pattern, and as for optics and modulating data, and the three-dimensional type of drive is not do restriction.
