Abstract

A practical fiber microbend measurement instrument and methods for fluid level are proposed in this paper. The principle of the two signals ratio measurement is introduced. The techniques of light feedback and phase-sensitive demodulation are used to stabilize the light source. Improvement in drift, noise, high reliability and long-term stability by means of taking these methods are also discussed.
