Examples
- Based on local coupling mode theory of graded index optic fiber wave guide , the variation regularity of coupling output light has been deduced when sound wave acts on single mode optic fiber coupler . and a new idea has been proposed that a novel sensor can be applied on detection of acoustic / vibration . the sensing element of sensor is the melting area of single mode coupler in which the feasibility of the new - type optic fiber sensor has been proved in experiment
本文从缓变光纤波导的局部耦合模理论出发，推导出了单模光纤耦合器耦合分光在声波作用下的变化规律，提出了以单模光纤耦合器的熔融区为传感元件的传感器在声振动信号检测中应用的新思想，并实验论证了这种新型光纤传感器应用于实际的可行性。
