the research of optical communication signal tracking has always been the focus of people’s attention. Aiming at the limitations of traditional optical communication signal tracking system, such as long tracking time and error, in order to improve the tracking accuracy of optical communication signal, an optical communication signal tracking system based on fuzzy mathematics method is proposed. First of all, the current research status of optical communication signal tracking, and find out the reasons for the poor tracking effect of optical communication signal, and then design the overall structure of optical communication signal tracking, and specifically realize the optical communication signal tracking based on fuzzy mathematics, finally carry out the optical communication signal tracking test, the results show that the maximum X-axis coordinate offset of the system is 9.32 μrad. When the frequency is 100 Hz, the MSE of the system is only 18.8 μrad. Under different frequencies, the pixel error of the system is ± 6, and the error is small. The optical communication signal tracking accuracy of the system is high, which effectively reduces the optical communication signal tracking error and improves the optical performance The result of communication signal tracking shows that the ideal tracking result of optical communication signal is obtained.
