Abstract
The present invention relates to a bidirectional remote laser communication apparatus. A remote data terminal (1) transmits data to be sent to a single-chip microcomputer (3) through a data communication interface (2), the single-chip microcomputer (3) sends the data to a laser emitting head (7) through a modulating and sending module (8), and converts a digital signal to a laser signal for sending out, when a laser receiving head (6) receives a laser communication signal, an analog signal is amplified by a receiving and amplifying circuit (5), and then input in a demodulated circuit (4) to be converted into the digital signalThen the digital signal is sent to the single-chip microcomputer (3) and the single-chip microcomputer (3) sends the received data to the remote data terminal (1) again through the data communication interface (2), and outputs communication receiving data.
