Abstract

As a widely used wavefront sensor in adaptive optics, Hartmann-Shack wavefront sensor (HSWFS) has a simple structure and high accuracy. However, the dynamic range and field of view of HSWFS are limited, preventing it from usage under strong turbulence conditions. Plenoptic wavefront sensor (PWFS) has the advantages of large dynamic range and detection field of view, which effectively compensates for the shortcomings of HSWFS. In this paper, we analyzed the performance of the PWFS theoretically and then verified by simulation. Because of the fundamental error in wavefront slope measurement of PWFS, the open-loop wavefront correction accuracy is unsatisfied and closed-loop correction is highly preferred.
