Paper Abstract

In recent years, the wavefront sensorless adaptive optics (AO) system receives extensive research and the model-based control AO system as one of the most systems will become the most promising one. The model-based AO control system depends on a linear relationship between second moments of the wavefront gradients and masked far-field intensity distribution. Before investigating whether the model-based control algorithm has a good correction capability, the linear relationship must be verified. In order to testify the linear relationship, an adaptive optics system experiment platform is established with a 37-element deformable mirror and a CCD camera. The CCD camera measures the information of far-field intensity distribution and the Hartmann Shack gets sensor information of wavefront distribution. The linear relationship is analyzed based on above the information. Result shows that there is a linear relationship between second moments of the wavefront gradients and masked far-field intensity distribution and the slop is 0.018, which is very close to the theoretical value 1 / (4π2).
