Abstract

The invention is directed at a sensor arrangement for measuring a physical parameter. The sensor arrangement includes a fiber grating sensor and an optical sensor for determining a wavelength characteristic of an output signal from the fiber grating sensor. The optical sensor comprises a radiation source and an interferometer, wherein the interferometer is configured for providing a combined signal from two mutually phase delayed fractions of the output signal to an output port to generate an output interference signal for enabling determination of the wavelength characteristic by an analyzer operatively connectable to the output port via the calculation of the phase of the output interference signal. The fiber grating sensor is a phase shifted type fiber grating sensor. Thereby a sensor arrangement is provided having a very high measurement resolution, enabling highly accurate measurement of strain or pressure on a sample, both statically and dynamically.
