| 摘 要： | 波前检测是天文望远镜自适应光学中的重要环节。四棱锥作为一种新型的波前检测元件,与其他传统的波前传感器相比,具有较高的灵敏度。特别是对于光干涉或拼接镜面望远镜而言,四棱锥波前传感器能够被用来检测子望远镜或子镜面之间的相对光程差,从而为干涉(或共相)的实现提供有效的检测信号。在分析四棱锥波前检测原理的基础上,阐述了单孔径条件下波前倾斜检测及双孔径干涉条件下相对光程差检测的软件仿真设计和阶段性成果,并简述了下一阶段的研究计划。

| Abstract: | Wavefront sensing is a crucial part of adaptive optics technology. The pyramid sensor (PS) has the advantage of higher sensibility than other classical wavefront sensors. PS is capable of detecting differential piston between sub-apertures of interferometer or elements of segment mirror. On the basis of analyzing pyramid sensor principle, a software simulation design including algorithm, some initial results and two conclusions about wavefront tip-tilt sensing of single-aperture telescope and differential piston sensing of double-aperture interferometer are discussed respectively. The next research scheme is also introduced briefly. |
