Design of a Dual Axis Photoelectric Tracking System Based on Four Quadrant Photoelectric Detector

摘要

With the energy and the increasingly serious environmental problems, making full use of solar energy has become the trend of development. As an important way of solar energy utilization, the normal operation of solar pumped lasers depends on the ability of the pumping source to accurately track the direction of the sun. However, the existing tracking system has poor stability and low tracking accuracy. In view of the above problems, an embedded two-axis photoelectric tracking system is proposed. The system is proposed based on a unique four-quadrant photoelectric detector, and adopts the control scheme of the solar orbital tracking method combined with the fine tuning of the four-quadrant photoelectric detector, which effectively improves the performance of the system. The precise positioning and tracking ability of the pump source to the solar azimuth ensures the stable operation of the pump source.
