摘　　要：本文对多模光纤数值孔径测量的激励条件进行了理论分析及实验研究.证明采用孔径匹配技术可以有效地提高数值孔径的测试精度.文中还指出,适当地增加被测光纤的长度和在测试时加入匹配液,都将有助于提高测试的准确度.The influences of stimulating conditions on the measurement of numerical aperture of multimode fiber are discussed theoretically and experimentally. It is proved that the aperture-couple technique can improve the precision efficiently. Additionally, we find that by increasing the length of the tested fiber and by using silicon oil to strip the cladding mode, the test accuracy will also be improved.
