Study on the response speed of fabry–perot interferometer gas pressure fiber sensor based on photonic crystal fiber and vernier effect

摘要

A fast response fiber-optic gas pressure Fabry-Perot interferometer is demonstrated. The results show that the response time is 218 and 208 ms, respectively, when the gas pressure increases from 140 to 142 PSI and decreases from 170 to 167 PSI.
