Abstract
A pressure-measuring device including an optical fibre with a thinned portion, a laser, called the heating laser, arranged to emit an optical wave, called the heating wave, into the thinned portion, a measuring means including a sensor that is arranged to measure a backscattered optical wave that is generated by an optical wave, called the interrogation wave, and that originates in the thinned portion of the optical fibre, and a processing unit arranged and/or programmed to measure a pressure of a fluid, preferably a gas, encircling the thinned portion, on the basis of the measurement of the backscattered wave.
