The sensor consists of a fiber-optic collimator and a PTFE diaphragm to form a Fabry-Perot interferometer. Due to the significantly increase in the slope of the sensor spectral sideband and the smaller Young’s modulus of the PTFE, a high response to both continuous and pulsed ultrasound with a high SNR of 42.92 dB in 300 kHz is achieved when the spectral sideband filter technique is used to interrogate the sensor.
