Paper Abstract

Sensitivity is one of the most important features for a sensor. The paper makes study on the photoelastic optic fiber pressure sensor. Based on the predecessor's work,the paper puts stress on the thin plate sensing element --- a new configuration of the photoelastic sensing element. The modulation theory of the thin plate sensing element is revised and perfected by a thorough theoretical analysis. The theory reveals that the adoption of thin plate sensing element can largely increase the sensitivity of the sensor by decreasing its thickness. In addition,an experimental prototype of photoelastic optic fiber pressure sensor with thin plate sensing element is provided. The experimental results coincide well with the theory, and relative error is less than 4% in total measuring range.
