【摘要】 角锥波前探测器是一种新型波前探测器,具有哈特曼波前探测器所不具有的优势。角锥波前探测器的探测光路较哈特曼探测器复杂,器件之间的相对关系决定了系统的静态像差,与湍流像差相耦合,影响探测精度。为了提高角锥探测器的探测精度,对探测器的精确校准进行了理论分析和实验验证,提高了系统对静态湍流像差的闭环校正能力。更多还原

【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 abberation 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.更多还原
