Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless laser communication device. Background technique [0002] Visible light communication technology refers to a communication method that uses light in the visible light band as an information carrier and directly transmits optical signals in the air without using optical fiber and other wired channel transmission media. [0003] In the prior art, physical implementation of visible light communication is divided into two parts: optical signal transmission and optical signal reception. Among them, the optical signal transmitting part includes: an input and processing circuit that converts the signal source signal into an electrical signal that is convenient for optical channel transmission, and an LED visible light drive modulation circuit that modulates the change of the electrical signal into a change in the intensity of the optical carrier; the optical signal rece...
