随着高质量光导纤维的出现,许多光导纤维器件相继问世。强度调制声光传感器也引起人们极大的关注。这种传感器可以建立在单模光纤端面的反射光强度调制的基础上,此时光线入射在光纤上的角度必须满足全反射条件。强度调制传感器也可以利用两根多模光纤之间
With the advent of high quality optical fiber, many optical fiber devices have come out. Intensity modulation acousto-optic sensor also caused great concern. This sensor can be based on the single-mode fiber end of the reflected light intensity modulation based on the incident light on the fiber angle must meet the total reflection conditions. The intensity modulation sensor can also use between two multimode fibers
