Abstract

The pyramid wavefront sensor (PWFS) is a novel sensor, equipped with superiorities in many aspects comparing with Shack-Hartmann wavefront sensor. The optical system of PWFS is more complicated, and relationships among different elements affect the static aberration of the system, which coupling with the turbulence would impact the sensing accuracy of the sensor. Aiming at improving the sensing accuracy, we analyzed the precise calibration of the system and verified the theory through experiments, which enhanced the closed-loop system’s ability to correct the static turbulence.
