Abstract

The comprehensive and high-performance adaptive optics test bench (CHAO) is an indoor adaptive optics system developed by the High-Resolution Solar Atmospheric Optical Detection Team at the Institute of Optics and Electronics, Chinese Academy of Sciences. It possesses the capability to test and validate cutting-edge technologies in the field of adaptive optics. In current stage, CHAO includes a conventional adaptive optics system and a ground-layer adaptive optics system. These two AO systems each consist of a 177-subaperture single-direction Shack-Hartmann wavefront sensor (SH-WFS) and a 55-subaperture multi-direction SH-WFS, sharing a 177-element deformable mirror. The real-time controller of CHAO employs a multi-core CPU architecture, enabling both two AO systems to operate stably at frequencies above 4000 Hz. Additionally, RESAO is equipped with both point target source and extended target source, along with a turbulence phase screen to simulate dynamic turbulence disturbances. This paper will provide a detailed introduction to the design, functionality, and current results obtained based on the CHAO.
