碩士 === 國立高雄第一科技大學 === 光電工程研究所 === 96 === In this thesis, it describes the design and fabrication of tracking sensor, and uses LED as the light sensor to cost-down. For the sensor structure , we design the large-scale angle for exterior sensor structure, and raise the tracking accuracy by interior sensor structure. In order to understand the acceptance of varied light energy to light-shift for sensors, we design the structure of sensor by FRED in order to stimulate light-shift, and fabricate the sensor as well as control the light source position by Single-Chip 8052. At last, we use light sensors structure with two-axis sun tracking system to track the sun light and the tracking accuracy can be less then 0.905 degrees.
