Abstract

Using interrelated check technology and a reference channel, one can realize compensation of unstable factors of an intensity modulated optic fiber sensor. The author analyzes the compensatory mechanism. Theoretic analysis and experimental results support the adoption of the compensatory technology. The optic fiber displacement sensing system can effectively compensate the influence on measuring accuracy and stability of various factors including light power fluctuation, reflector surface property, optic fiber transmission loss changes, and environmental light interference
