index sensor meaning in Chinese

索引传感器

Compared with d - shaped fiber , the d - shaped fiber bragg grating index sensor is more precise and reliable because the sensed information is encoded into wavelength , which is an absolute parameter , the output does not depend on the light levels , loss in the connecting fibers and couplers , or source power
光纤布喇格光栅传感器以波长偏移和功率变化同时作为传感度量，由于波长检测对光功率涨落不敏感，相对于只以功率变化作为传感度量的传感器件，具有更高的传感精度和准确性。
