Abstract
An extrinsic fiber Fabry-Perot( F-P) explosion pressure sensor is designed
which has diaphragm type structure and F-P signal is demodulated with three-wavelength method. Pressure load experiments prove that the developed F-P pressure sensor has good linearity and high frequency response
and will not be influenced by electromagnetic interference
so it is able to be used in measurement of dynamic pressure of explosion.
