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.

Fiber Optic Gas Sensor Drift
Serious sensor drift (a gradual decrease in accuracy on a sensor) might indicate that a sensor will require a gas calibration, or it might imply a physical problem with a sensor or with the monitor's electronics. Very minor signal fluctuation happens naturally on most sensors due to minor fluctuations in temperature, pressure, and air concentration. Fiber optic sensors' inherent benefits of lightweight, compact size, and low attenuation were actively leveraged to overcome. Spectroscopic Optical Fibre Sensors Generally, spectroscopic techniques have been applied to fibre-optics sensors and are relatively successful in gas sensing applications.
