Abstract
The skylight background and the noise generated by the detection device system in adaptive optical system have a great impact for the spot detecting precision. In order to eliminate their affects, a wavefront spot signal extraction system is designed and implemented in this paper, and the effect of the extraction and the precision are tested in the indoor adaptive optics precision tracking system. The experiment results show that the design is better in extracting the target spot; the centroid accuracy after processed is higher. In the other hand, the processing time delay is small, which can meet the adaptive optics system’s real time requirement.
