Multichannel wireless laser communication apparatus

The utility model discloses a multichannel wireless laser communication apparatus. The apparatus comprises an emitter portion and a receiver portion. The emitter portion comprises a source input interface, a laser source, an incident optical path, a digital micro-mirror device, an emitting optical path and an emitter control circuit. The receiver portion comprises a receiving optical path, a photoelectric sensing array, a receiver control circuit and a sink output interface. The working process is as follows: electric signals are converted into optical signals for output at an emitter end by use of the micro-mirrors of the digital micro-mirror device, the optical signals are recovered to the electric signals at a receiver end by use of the photoelectric sensing array, and multichannel wireless laser communication is realized by use of the characteristic that the digital micro-mirror device comprises as many as millions of micro-mirrors. The multichannel wireless laser communication apparatus solves the problems of few channels of a conventional wireless laser communication system and quite slow system transmission rate, thereby being feasible.
