自适应光学幸运成像仪(AOLI)是一种正在开发的新仪器,用于演示大型地面望远镜在可见光区的近衍射极限成像。本文介绍了该仪器的自适应光学系统,包括大行程变形镜、固定元件非线性曲率波前传感器和光子计数EMCCD探测器。我们描述了波前传感器的光学设计,其中两个光子计数CCD提供总共四个参考图像。系统的光学特性的模拟进行了讨论,其相关性低,高阶AO系统。介绍了高速波前重建算法的发展和优化。最后,我们讨论了仿真结果,以证明系统的灵敏度。
The Adaptive Optics Lucky Imager (AOLI) is a new instrument under development to demonstrate near diffraction limited imaging in the visible on large ground-based telescopes. We present the adaptive optics system being designed for the instrument comprising a large stroke deformable mirror, fixed component non-linear curvature wavefront sensor and photon-counting EMCCD detectors. We describe the optical design of the wavefront sensor where two photoncounting CCDs provide a total of four reference images. Simulations of the optical characteristics of the system are discussed, with their relevance to low and high order AO systems. The development and optimisation of high-speed wavefront reconstruction algorithms are presented. Finally we discuss the results of simulations to demonstrate the sensitivity of the system.
