Dataset for "All-fibre wavefront sensor"

We have developed a tip-tilt wavefront sensor based on a tapered three-core optical fibre. In this device, a coupled region at the sensing tip of the fibre converts phase information from an incoming wavefront into intensity information within each of the cores. The sensor uses minimal information to infer tip-tilt and is compatible with remote detector arrays, making it highly relevant for use in ground-based astronomical telescopes. This repository contains three sets of 49 near-field images, which capture the response of our all-fibre wavefront sensor to incoming wavefronts of changing tip/tilt. We have included an analysis/plotting script (in Matlab) to evaluate the centroid positions from the acquired images and plot these alongside analytical values. These files comprise the complete set of experimental results presented in "All-fibre wavefront sensor".

本研究团队研制了一款基于锥形三芯光纤的倾斜倾斜波前传感器。在该装置中，光纤传感端的耦合区域将入射波前的相位信息转化为每个光纤芯中的强度信息。该传感器通过最小的信息量推断倾斜倾斜状态，且与远程探测器阵列兼容，因此在地面天文望远镜的应用中具有极高的相关性。本仓库包含三组共49张近场图像，这些图像捕捉了我们的全光纤波前传感器对变化倾斜倾斜的入射波前的响应。我们还包含了一个分析/绘图脚本（Matlab 编写），用于从获取的图像中评估质心位置，并将这些位置与解析值一同绘制。这些文件构成了《全光纤波前传感器》中展示的完整实验结果集。
