| Abstract: | To realize the automatic sun-tracking based on four-quadrant detector,the working principle of four-quadrant detector is firstly analyzed and the reason of selecting four-quadrant detector is explained.The setup based on four-quadrant detector for sun-tracking is introduced,the possibility of deviation influence,such as geometry position of the sun spot,installation position between aperture iris and four-quadrant detector is deeply investigated,the consistency between four-quadrant detector and its I—V conversion circuit is analyed, and the influence of consistency on tracking precision is evaluated.The reason and rationality of deviation existence on four-quadrant detector voltage for sun-tracking are introduced.The experiment demonstrated that the designed device based on four-quadrant detector is suitable for high-precision sun-tracking. |
