摘要
讨论了1×8移动光纤式光开关及其控制程序,通过控制步进电机的微位移实现多个通道之间的切换。将该光开关应用到光纤光栅压力传感解调系统中,控制其分时接通解调器件DWDM的各个通道和光电探测系统,只需一个光电探测器就可完成原本需要多个探测器的探测工作,大大简化了解调系统结构,提高了系统总体性能。
1×8 mobile fiber optical switch and its control program were discussed. Switching between multiple channels can b realized by controlling the micro displacement of the stepper motor. The optical switch is applied to the fiber Bragg grating pressure sensing demodulation system. Controlling the optical switch connecting each channel of DWDM and photoelectric detector can greatly simplify the structure and improve the overall performance of the system or only one photo detector is used instead of multiple detectors.
