基于傅里叶变换红外光谱仪，建立了中空纤维损耗光谱测量系统。可以测量长度范围从几厘米到3米的中空纤维的损耗谱。设计和制造了两种光源耦合器，以实现稳定的耦合和可重复的光谱。一种是短波导，另一种是锥形管。两者都内涂有银层，输出端的内径与被测中空纤维的内径相同。使用这两个耦合器时，从理论上和实验上讨论了测量系统的特性。测量了几种中空纤维，并讨论了损耗谱的特性。显示测量的损耗值取决于耦合器的输出发散角。与波导耦合器相比，锥形耦合器具有更大的输出发散度并导致更高的测量损耗。
Based on the Fourier transform infrared spectrometer, a system for measuring the loss spectrum of hollow fiber is established. Loss spectra can be measured for hollow fibers with length ranging from several centimeters to 3 m. Two kinds of light source coupler are designed and fabricated for achieving stable coupling and a repeatable spectrum. One is a short waveguide, and the other is a tapered tube. Both are inner-coated with a silver layer and they are of the same inner diameter at the output end as the measured hollow fiber. Characteristics of the measuring system are discussed theoretically and experimentally when using the two couplers. Several kinds of hollow fibers are measured, and the properties of the loss spectra are discussed. The measured loss value is shown to be dependent on the output divergence angle of the coupler. The tapered coupler has a larger output divergence and causes higher measured loss than that of the waveguide coupler.
