提出了一种测定光纤焦比退化的简便方法。该方法包括分割来自测试光纤的光并记录在两个不同且已知的光路上传播的环形图案。这种新方法对于测试新的多目标天文光谱仪所需的许多纤维将是有价值的。
A simple method for determining the focal ratio degradation of optical fibers has been developed. The method involves splitting the light from the test fiber and recording ring patterns that have traveled over two different, and known, optical paths. This new method will be valuable for testing many fibers as will be needed for new multiobject astronomical spectrographs.
