Abstract
The utility model relates to a bidirectional remote laser communication instrument. A remote data terminal (1) transmits to-be-sent data to a single-chip microcomputer (3) through a data communication interface (2). The single-chip microcomputer (3) transmits the data to a laser emission head (7) through a modulation sending module (8), so digital signals are converted to laser signals and are sent out. When a laser receiving head (6) receives the laser communication signals, a reception amplification circuit (5) amplifies analog signals, and then the signals are input to a demodulation circuit, and the analog signals are converted to digital signals. The digital signals are sent to the single-chip microcomputer (3). The single-chip microcomputer (3) sends the received data to a remote data terminal (1) through the data communication interface (2), so that the communication reception data is output.
