| Abstract: | Requirements of high-precision spot detection in laser communication ATP fine tracking systems are analyzed, and design principles of a spot-detecting camera as well as hardware implementation methods of spot centroiding algorithm are explained. According to the needs of performance parameters of laser communication ATP fine tracking system, a high-performance spot-detecting camera is designed and manufactured. Test results verify that, frame frequency of the camera is up to 2.5 kHz, spot position extractio... |
