Because of the digitally rebalanced circuit , the sensor is capable of achieving better static and dynamic characteristic , higher sensitivity and stability . in this paper , the propagation path of light in the step index fiber and graded index fiber is introduced firstly . then the paper sets up the coupled power model and develops the coupling function 在文中,首先介绍了光线在阶跃型光纤和梯度折射型光纤中的传播路径,以及在一端镀有反射膜的1 4波节长度的grin透镜中的成像规律,并推导了光功率耦合函数。
step index fiberとは意味:<→STEP-INDEX fiber> step index fiber перевод:опт. волокно со ступенчато-изменяющимся показателем преломления, волокно со ступенчатым изменением показателя преломления
