Method of communication link acquisition using search pattern
摘要
說明書
The receiver 240 includes a light position sensing device to detect the optical beam 210. In some examples, the light position sensing device includes, but is not limited to, a lateral position device, a charge-coupled Device (CCD) camera, a photodetector, a quad-cell, or a CMOS sensor to detect the optical beacon laser. The receiver 240 converts the received optical beam 210 into an electric signal using the photoelectric effect.
The optical system 250 may be configured to transmit the optical beams, such as, for example, optical communication beam (not shown) or beacon beam 24, as well as receive the optical beams and provide the received optical beams to the receiver 240. For receiving optical beams, the optical system 250 and/or the receiver 240 may include, but are not limited to, a de-multiplexer, an optical pre-amplifier, photodiodes, the photo receiver, transimpedance amplifiers, clock/phase recovery circuits, decision circuits, and/or forward error correction circuits. The optical system 250 and the receiver 240 may be configured to acquire image frames, and the receiver 240 may further be configured to process the acquired image frames to determine a location of the received optical beams.
