“…Blackbody radiation fiber-optic temperature sensors are particularly attractive for applications where transient surface high-temperature measurements are required, such as explosive flames, rocket engine plume flames, gas turbine combustors, or high-temperature reactors [ 9 ]. The structure of the sensor, the selection of the blackbody cavity coating material, and the uncertainty analysis are the keys to the development of blackbody radiation high-temperature sensing technology.…”

High-temperature measurements above 1000 °C are critical in harsh environments such as aerospace, metallurgy, fossil fuel, and power production. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic interference, remote detection, multiplexing, and distributed measurement advantages. This paper reviews the sensing principle, structural design, and temperature measurement performance of fiber-optic high-temperature sensors, as well as recent significant progress in the transition of sensing solutions from glass to crystal fiber. Finally, future prospects and challenges in developing fiber-optic high-temperature sensors are also discussed.

Knowledge of material emissivity maps and their true temperatures is of great interest for contactless process monitoring and control with infrared cameras when strong heat transfer and temperature change are involved. This approach is always followed by emissivity or reflections issues. In this work, we describe the development of a contactless infrared imaging technique based on the pyro-reflectometry approach and a specular model of the material reflection in order to overcome emissivities and reflections problems. This approach enables in situ and real-time identification of emissivity fields and autocalibration of the radiative intensity leaving the sample by using a black body equivalent ratio. This is done to obtain the absolute temperature field of any specular material using the infrared wavelength. The presented set up works for both camera and pyrometer regardless of the spectral range. The proposed method is evaluated at room temperature with several heterogeneous samples covering a large range of emissivity values. From these emissivity fields, raw and heterogeneous measured radiative fluxes are transformed into complete absolute temperature fields.

CVT tractor has the characteristics of high-energy consumption and low-energy efficiency, which makes the monitoring of its energy consumption significant. According to the characteristics of the CVT tractor, a high-speed and high-precision temperature measurement system was built in this article. By the late experimental demonstration and data processing, the temperature field was simulated by the simulation of the ANSYS and the analysis of Matlab. This system was used to realize the measurement of temperatures with a microcontroller, which mainly included a AT89S52 microcontroller, temperature sensors, a keyboard and a display circuit. It can accomplish the measurement of the temperatures from eight different directions in real time, and it can display and set temperatures on the LCD screen as well. When the real-time temperature was higher than the temperature set before, the buzzer would alert automatically. The late tests showed that the dynamic temperature field measurement system had the advantages of being convenient and practical, which can not only measure the temperature of the CVT tractor, but also measure temperatures of various kinds of dynamic temperature fields after some specific improvements. The temperature measurement system has potentials in various kinds of fields if it was developed to meet the need of humans.
