Paper Abstract

Micrometric displacement sensor with optical fiber was employed to inspect deformation of membrane box with air pressure changing, in order to avoid the defects in inspecting deformation, or improve and optimize performances of the sensors. A multi-path optical fiber sensor was utilized to measure the displacement, so that sensitivity is increased, and a little changing in air pressure may be measured. The relation between optical fiber sensor output changes and atmospheric pressure changes was standardized with a standard air pressure gauge. A setup for measuring atmospheric pressure was formed, the experiment results indicate that measurement range is 500-1060hpa, resolution is 0.2hpa, and accuracy is ±0.2hPa.
