AI 中文摘要
高对比度成像需要极其灵敏的波前传感来校正大气效应和表面误差。虽然波前传感器灵敏度的极限是众所周知的，但一个能达到这些极限的实用、稳健设计仍然难以实现。这项工作进一步研究了PIAA-ZWFS（相位诱导振幅切趾-泽尼克波前传感器）。此前已开发出优化其设计的框架，在存在相位像差时最大化每帧的费舍尔信息。在此研究中，考察了系统中各种制造和对准误差对整体性能的影响。采用传统蒙特卡洛采样和使用自动微分模拟器的二阶展开。在制造的典型误差值下，PIAA-ZWFS的性能不会显著下降。
英文摘要
High-contrast imaging demands extremely sensitive wavefront sensing to correct atmospheric effects and surface errors. While the limits of the sensitivity of a wavefront sensor are well known, a practical, robust design that saturates these limits remains elusive. This work further investigates the PIAA-ZWFS (Phase-Induced Amplitude Apodization-Zernike Wavefront Sensor). In previous work, we developed a framework to optimise its design, maximising Fisher information per frame in the presence of phase aberrations. In these proceedings, we study the effect of various manufacturing and alignment errors in the system on the overall performance. We employ both traditional Monte Carlo sampling and a 2nd order expansion using our auto-differentiable simulator. The performance of the PIAA-ZWFS is not significantly degraded by these errors at values typical for manufacturing.
