Abstract

The invention discloses a beacon light spot stable positioning system in wireless optical communication and an implementation method of the beacon light spot stable positioning system. The system and the implementation method solve the problems that an existing light spot mass center positioning algorithm is low in positioning stability and a detection target is prone to be lost in moderately strong turbulent flow. The system comprises a receiving antenna, a gimbal mount, a CCD sensor, an image processor and a motion controller. A beacon light source is transmitted through a transmitting antenna and received by the receiving antenna located at the front end of the gimbal mount, the CCD sensor is connected to the rear end of the gimbal mount, and the CCD sensor is sequentially connected with the image processor and the motion controller. The receiving antenna is used for receiving beacon light transmitted through the atmosphere, and a collimator made of full stainless steel is adopted in the receiving antenna, wherein the focal distance of the collimator is 300 mm.

Description
