Adaptive Optics: Image Restoration

Scientific paper

The paper reports the first experiment of a 21-element adaptive optical system for stellar objects on the Yunnan Observatory 1.2-m telescope and presents the improvements of the system for low-light-level stellar objects. The experimental results show that the adaptive optical system can work satisfactorily when the photon counts are as low as 93 per subaperture per integrating time. The experiments show that the effects of adaptive optics in reducing the divergence and wandering of the image spot, in improving resolution, and in increasing image contrast are significant.
