“…Simultaneous measurement of RI and temperature with corresponding sensitivities of up to 26.087 nm/RIU (blueshift) and 0.077 nm/°C (redshift) was achieved. In other work, the RI and temperature sensitivities for a device comprising two bi-tapers and an LPG were 108.16 nm/RI and 0.12 nm/°C, respectively [92].…”

The development of reliable, affordable and efficient sensors is a key step in providing tools for efficient monitoring of critical environmental parameters. This review focuses on the use of tapered optical fibres as an environmental sensing platform. Tapered fibres allow access to the evanescent wave of the propagating mode, which can be exploited to facilitate chemical sensing by spectroscopic evaluation of the medium surrounding the optical fibre, by measurement of the refractive index of the medium, or by coupling to other waveguides formed of chemically sensitive materials. In addition, the reduced diameter of the tapered section of the optical fibre can offer benefits when measuring physical parameters such as strain and temperature. A review of the basic sensing platforms implemented using tapered optical fibres and their application for development of fibre-optic physical, chemical and bio-sensors is presented.

Temperature Measurement Using Optical Fiber Methods: Overview and Evaluation

et al. 2020

The paper deals with the overview of fiber optic methods suitable for temperature measurement and monitoring. The aim is to evaluate the current research of temperature measurements in the interval from temperature close to 0 up to 1000°C. Since the measuring chain is a functional combination of optical methods, optical fiber properties, and other photonic elements together with control electronic circuits, it is necessary to find a suitable compromise between the chosen measurement method, measuring range, accuracy, and resolution. Optical fiber sensors can be used in cases where standard electrical measurement methods cannot be used. These may be areas with high electrical and magnetic interference or critical areas. Therefore, there is intensive development of optical and fiber optic methods based on blackbody and greybody radiation, luminescence, fiber Bragg gratings (FBGs), and interferometers.

“…For example, the GaAs sensor uses the temperature dependency of the GaAs translucence to determine the temperature [68]. Other sensor types are Mach-Zehnder interferometers, silicon reflection sensors, FBG sensors, phosphorescence sensors, Fabry-Pérot spectrometers [69][70][71], and so on. All previous types can be utilised for the transformer application.…”
