Temperature Measurement Using Optical Fiber Methods: Overview and Evaluation

Abstract

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.

Feasibility and Error Analysis of Using Fiber Optic Temperature Measurement Device to Evaluate the Electromagnetic Safety of Hot Bridge Wire EEDs

“…From Equation (17), the temperature rise of the bridge wire under pulse train injection is related to the amplitude, repetition frequency, and pulse width of the pulse train.…”

“…The temperature measurement method involves monitoring the bridge wire EEDs electromagnetic safety assessment by monitoring the temperature response of the bridge wire. Fiber-optic temperature sensing devices are commonly used in current experiments of temperature measurement [16,17]. Wang B. et al [18,19] proposed an equivalent method for testing the electromagnetic margin of EEDs in a strong electromagnetic environment.…”

Ratiometric Upconversion Temperature Sensor Based on Cellulose Fibers Modified with Yttrium Fluoride Nanoparticles

“…Conventional methods of temperature determination such as volume expansion thermometers, thermocouples, or thermistors are often insufficient, because there is a need for fast, remote, and real-time measurements that provide high spatial and temperature resolution [ 6 , 14 , 15 ]. Additionally, in many cases (for example, in magnetic resonance imaging (MRI)), any electromagnetic interferences (EMI) or galvanic connections are highly undesirable, and thus other nonelectrical methods of temperature measurement are sought [ 6 , 16 , 17 , 18 ]. Therefore, optical temperature sensors (e.g., based on fiber Bragg gratings, interferometers, thermography, Raman scattering, or luminescence) have become increasingly popular in the past few years because they meet the above requirements for temperature measurement [ 16 , 17 , 18 , 19 , 20 , 21 ].…”

Hilbert Transform Approach to Central Wavelength Detection for Fiber Bragg Grating Sensors

“…Bu fiziksel büyüklüklere, kuvvet, sıcaklık, gerilim vb. örnek verilebilir [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Bu tip sensörler birçok avantaja sahiptir, örneğin elektromanyetik alanlardan etkilenmezler düşük fiyatlıdırlar, pasif yapıdadırlar, bulundukları yerde elektrik ihtiyacı duymazlar, periyodik bakım gerektirmezler vb.…”
