摘要

为开展提高光纤焦比退化测量精度方法的研究, 提出了一种基于四象限探测器的光纤焦比退化的测量方法。该方法是光纤的出射光斑打到四象限探测器上, 通过偏转镜扫描四象限探测器靶面, 获得探测器上的光斑位置灵敏度, 间接获得出射光斑实际尺寸, 进而得出光纤的焦比退化。并对光斑位置灵敏度与光斑半径的关系进行了分析, 同时探究了四象限探测器的沟道宽度对光纤焦比退化的影响。

Abstract

A method of measuring focal ratio degradation of fibers based on a four-quadrant detector was proposed to improve the measurement accuracy of focal ratio degradation in fibers. The output spot of fibers was re-imaged on to the four-quadrant detector, and the spot position sensitivity of detectors was got through scanning the surface of the four-quadrant detector with a steering mirror, the actual size of the output spot and focal ratio degradation were measured indirectly in turn in this method. The relationship between the spot position sensitivity and the spot radius was deduced in detail. Meanwhile, the influences of the channel width of four-quadrant detectors on the focal ratio degradation were seriously studied.
