论文摘要
交叉的波前传感器（WFS）是一个瞳孔波前传感器，可测量波前的第一衍生物。它是由三个主要组件制成的：由正弦函数的产物构建的梯度传输滤波器（GTF）在光轴周围旋转了45度，在测试光学系统的焦点和检测器阵列上，位于与学生相结合的平面上的检测器阵列的焦点，一个2x2 mini镜头阵列（MLA）。基本原理包括同时获取四个瞳孔图像，每个图像都是从GTF后面的不同点观察到的。在证明波前重建能力的模拟工作之后，我们现在处于实验室中原型的实现阶段。交叉的WFS可以在测试光学的瞳孔上同时实现高空间分辨率，并且与激光互动计达到的绝对测量精度相当。在本文中，我们介绍了七个自定义的相掩码并对其进行测量。首先进行了测试和结果，根据我们探讨了越过的sine wfs的性能，并与激光互换的效果进行比较
The crossed-sine wavefront sensor (WFS) is a pupil plane wavefront sensor that measures the first derivatives of the wavefront. It is made by three main components: a gradient transmission filter (GTF) built from a product of sine functions rotated by 45 degrees around the optical axis, a 2x2 mini-lens array (MLA) at the focus of the tested optical system and a detector array located on a plane conjugated to the pupil. The basic principle consists in acquiring four pupil images simultaneously, each image being observed from different points located behind the GTF. After the simulation work which demonstrated the wavefront reconstruction capability, we are now in the phase of implementation of the prototype in the lab. The crossed-sine WFS could achieve a simultaneous high spatial resolution at the pupil of the tested optics and absolute measurement accuracy comparable to that attained by laser-interferometers. In this paper we introduce seven customized phase masks and make measurements of them.First tests and resultsare demonstrated, based on which we explore the performance of our crossed-sine WFS and make comparisons with that of the laser-interferomete
