论文摘要
为了达到新一代基望远镜的全部潜力，需要对该相进行极好的调整。因此，检测前的波前控制和校正已成为实现目标性能的仪器的基石之一，尤其是用于高对比度成像。精确波前控制的关键特征依靠波前传感器（WFS）。我们提出了一种设计新的傅立叶过滤WF的策略，该WFS编码与基本光子效率极限的相关相位。这种策略似乎很有希望，因为它生成了适合不同学生形状配置的高灵敏传感器。
To reach the full potential of the new generation of ground based telescopes, an extremely fine adjustment of the phase is required. Wavefront control and correction before detection has therefore become one of the cornerstones of instruments to achieve targeted performance, especially for high-contrast imaging. A crucial feature of accurate wavefront control leans on the wavefront sensor (WFS). We present a strategy to design new Fourier-Filtering WFS that encode the phase close from the fundamental photon efficiency limit. This strategy seems promising as it generates highly sensitive sensors suited for different pupil shape configurations.
