In order to reduce the impact of backlight noise and atmospheric changes on optical communication, an optical communication tracking detection system based on virtual instrument technology is designed. The virtual instrument technology is used to develop system micro-components and software functions. The tracking detection based on median filtering and centroid algorithm Function Development Support Software. Systematic antenna module in the laser and modulator selection, through a reasonable angle of beam emission high-precision laser beam. Using the virtual instrument detection module to detect the laser beam, the control module locates and distributes the detection result. The detection and tracking module performs beam alignment and tracking based on the detection result and the basic information of the laser beam to achieve high-precision optical communication. Experiments prove the advantages of high tracking accuracy in many situations.
