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,首先介紹了光線在階躍型光纖和梯度折射型光纖中的傳播路徑,以及在一端鍍有反射膜的1 4波節(jié)長度的grin透鏡中的成像規(guī)律,并推導(dǎo)了光功率耦合函數(shù)。
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
