COMBINED FIBER OPTIC SENSOR Russian patent published in 2022 - IPC G01L11/02 G01K11/02 

Abstract RU 2786357 C1

FIELD: pressure measuring.

SUBSTANCE: invention relates to the field of measuring hydrostatic and rapidly changing pressure using optical means. The sensor contains two sensitive elements (SE) of pressure and temperature, based on the Fabry-Perot interferometer (FPI) in such a way that the second reflective surface of the FPI of the first SE is simultaneously the first reflective surface of the FPI of the second SE.

EFFECT: improving the accuracy of temperature and pressure measurements.
