  • Principle of Fiber Optic Temperature Sensors

    Principle of Fiber Optic Temperature Sensors

    The principle of operation is based on the temperature dependence of the bandgap of GaAs. The GaAs crystal fixed on the tip of the fibre will be transparent at a wavelength above 850 nm. The position of the band edge is temperature-dependent and is shifted about 0.4 nm/K. The light is directed via the optical fibre to the crystal, where it is absorbed and partially reflected into the fibre. A miniature spectrometer provides a spectrum with the position of the band edge, from which the temperature is calculated.
