Abstract: Wireless laser communication has numerous advantages that include high transmission rate, strong anti-jamming ability, low power consumption, etc. In this paper, the red light with the wavelength of 650 nm is used as the signal carrier to design a transceiver circuit for wireless laser communication. And we elaborate the designed principles and methods of laser transmitting circuit and photoelectric receiving circuit. In proposed system, the transmitting circuit has the functions of automatic power control, fault indication and current monitoring, while the receiving circuit has the functions of signal amplification, photocurrent monitoring and automatic noise. Furthermore, the performance of proposed circuit is tested by using the experimental platform, and the correctness and rationality of designed circuit are verified. The exprimental results showed that the designed circuit can achieve reliable transmission when the transmission rate is 16 Mbit/s.

Key words: wireless laser communication, transmitting circuit, receiving circuit
