摘　　要：介绍了一种测量光纤束透过率的方法。光纤束透过率能有效表征光纤的透光性能,其透过率的值将直接影响它在众多科学领域中的应用,因此准确测其透过率的值很有必要。设计是根据著名的朗伯定律中透射比的求解来设计的,其值即为出射光强与入射光强的比值。据此定律还可得出光纤束的衰减系数。利用截断法和倒序法相结合的方法测出了具有一定长度的光纤束的透过率。通过其样品求得透过率值约为78%,衰减系数值约为0.248m^(-1)。此系统操作方便,测试结果客观、准确,可以完成对光纤束透过率的测量。This article introduces a method for measuring the transmittance of an optical fiber bundle.The transmittance of an optical fiber bundle can effectively characterize the light transmittance of an optical fiber,and its transmittance value will directly affect its application in many scientific fields,so it is necessary to accurately measure its transmittance value.The design is based on the solution of the famous Lambert′s law of transmittance,and its value is the ratio of the emitted light intensity to the incident light intensity.According to this law,the attenuation coefficient of the fiber bundle can be obtained.The transmittance of a fiber bundle with a certain length is measured by the combination of the truncation method and the reverse order method.The transmittance value obtained from the sample is about 78%,and the attenuation coefficient value is about 0.248 m-1.This system is easy to operate,the test results are objective and accurate,and it can complete the measurement of the optical fiber bundle transmittance.
