| Abstract: | A noval fiber-loop ring-down spectroscopy based on multimode fiber is proposed for pressure measurement.When an external pressure is applied to a section of the fiber,the light pusle traveling through the fiber-loop changes.Pressure measurement is achieved in a time domain by measuring the ring-down time.The pressure sensing system is demonstrated with good linear response,larger dynamic range,good stability and high sensitivity. |
