受 1× 3光开关控制 ,脉冲宽带光波被导入 3× 5光栅传感器阵列中待查询的任一光栅串 ,根据传感元间光纤延时程度的不同 ,利用电子程控开关 ,对来自不同光栅信号的选择通导 ,借助非平衡迈克耳孙扫描干涉仪对传感信息进行解调 ,成功地实现了空、时分复合复用传感 Under the control of a 1 × 3 optical switch, a pulse broad band light wave is introduced into any grating string to be queried in a 3 × 5 grating sensor array. According to the delay degree of the fiber between sensing elements, an electronic program-controlled switch is used to control the light from different grating signals The choice of pass, with non-equilibrium Michelson scanning interferometer to demodulate the sensing information, the successful realization of the space-time multiplexing multiplexed sensing
