Optical fiber displacement sensors (OFDS) convert mechanical displacement into a measurable optical signal by exploiting modulations of light intensity, phase, wavelength, or backscatter within optical fibers — delivering immunity to electromagnetic interference, sub-micron. Optical fiber displacement sensors have evolved from laboratory interferometers into a multi-vertical industrial technology — now converging with AI, IoT, and distributed sensing architectures capable of centimetre-scale spatial resolution. Additionally, integration into the case of a second fibre Bragg grating enables optimal integrated temperature compensation.
