论文摘要
我们报告锥形的三核光纤，该光纤可用作倾斜波沿传感器。在此设备中，在纤维的传感尖端处的几毫米的耦合区域将脆弱的相信息从进入的波前转换为每个核心内的强度强度信息。强度信息可以轻松地转换为小范围上的线性波前误差，使其非常适合闭环系统。传感器使用最小信息来推断倾斜倾斜，并且与远程检测器阵列兼容。我们探索其在自适应光学中的应用，并提出验证案例，以显示其适用于天文学。
We report on a tapered three-core optical fibre that can be used as a tip-tilt wavefront sensor. In this device, a coupled region of a few millimetres at the sensing tip of the fibre converts fragile phase information from an incoming wavefront into robust intensity information within each of the cores. The intensity information can be easily converted to linear wavefront error over small ranges, making it ideal for closed loop systems. The sensor uses minimal information to infer tip-tilt and is compatible with remote detector arrays. We explore its application within adaptive optics and present a validation case to show its applicability to astronomy.
