摘要

A highly sensitive optical fiber anemometer is demonstrated by using a polymer Fabry-Perot interferometer (FPI) fabricated on the tip of a single-mode fiber. The polymer FPI absorbs light injected by the broadband light source and generates heat. Its temperature is therefore increased to a certain value which is higher than that of the environment. When airflow is applied, its temperature is reduc...
