Abstract

The designs of existing Adaptive Optical System are "unadaptive" themselves, it means the parameters of the systems, such as subaperture diameter d, dynamic range of wavefront distortion correction, frequency bandwidth, etc., are fixed. Since these parameters were mainly decided according to some statistic values of atmospheric disturbance and detected objects, those systems don't have the ability to adapt the variation of observation conditions to obtain optimized operating parameters in real time though it is necessary in many cases. In this paper, a concept of an Adaptation of Adaptive Optical System(AAOS) is proposed. The AAOS has certain real time optimization ability against the variation of the brightness of detected objects m, atmospheric coherence length r0 and atmospheric time constant ? by means of changing subaperture number and diameter, dynamic range, and systems' temporal response. The necessity of AAOS using a Hartmann-Shack wavefront sensor and some technical approaches are discussed. Scheme and simulation of an AAOS with variable subaperture ability by use of both hardware and software are presented as an example of the system.
