spurious coupling

基本解释

But spurious polarization coupling caused by many factors will affect the performance of PMF, and therefore reduce fiber-optic gyro's quality and measuring precision.
由于多种因素使得保偏光纤内部产生了寄生偏振耦合，影响了保偏光纤的性能，并因此降低了光纤陀螺的质量和测试精度。
Fiber polarization coupling analyzer researched by this thesis is used to detect the coupling position and intensity of spurious polarization coupling point along the PMF.
本文所研究的光纤寄生偏振耦合测试仪是以白光干涉为依据，测量保偏光纤中寄生偏振耦合点的位置及耦合强度。
First, it uses a new kind of coupling method in the SIR filter and second, it combines the DGS structure with the newly designed filter to provide more suppression in the spurious passband.
采用了DGS结构和新型的耦合方式，增强了耦合，为滤波器提供了更多的零点抑制寄生通带的影响。
