| 摘 要： | 光纤的数值孔径NA(numericalaperture)是光纤的一个重要光学参数,它在一定程度上表征光纤集光能力和与光源耦合的难易程度,同时对连接损耗及衰减特性也有影响.它与光纤传输系数的计量有密切的关系,对光纤的传输带宽有着很大的影响.光纤数值孔径的测量方法有多种,但所需的实验装置都比较复杂.本文提出了一种利用光纤传感实验仪实现光纤数值孔径测量的简单方法,该测量方法可靠易行.

| Abstract: | The numerical aperture is an important parameter of optical fiber. It represents the ability of optical fiber receiving light and degree of light source coupling. Simultaneously, it affects the connecting loss, decay character, computation of transmission coefficient and the transmission bandwidth of optical fiber. There are many measurement methods of the NA, but they require complicated devices. This paper puts forward a new measurement method of the NA by the Fiber-optic Sensing Instrument. Comparing with other methods, it is simple and credible. |
