光纤传感器中的补偿技术

The Compensation Technology in Optical Fibre Transducers

振幅调制型光纤传感器采用光桥式补偿结构后,有效地减小因环境因素变化而导至的误差,该技术应用于光弹效应光纤压力传感器及激光雷达储油罐液位测量中,取得明显的效果。

By adopting optical bridge type compensationstructure, the error of the amplitude modulated optical fibre transducers caused by varying environmental factors can be eliminated effectively. Obvious effects have been obtained by using this technology in opto-elastic optical fibre transducers and laser radar level measurements of oil tanks.
