包层折射率 meaning in Chinese

cladding index

The term of mode - filtered light refers to the observation that light initially propagating down an optical fiber can be decoupled from that fiber by increasing the cladding ri at the core / clad interface with a permeating analyte , thus changing the allowable propagating modes within the fiber , resulting in a continuous and nearly linear increase in mode - filtered light with increasing cladding ri
所谓模式滤光，是指分析对象进入光纤包层引起光纤芯包界面的折射率增加，导致光纤内的部分传导模不满足传导条件而从光纤的包层中侧漏出来的光学信号，它与包层折射率的增量在一定条件下线性相关。
