“…Luminescence time response measurement is the most commonly used method because it is relatively simple and intensely independent of the amount of excited light [15,45]. Crystals showing the temperature dependence of the lifetime of excited light-generating electrons are ruby (chromium-doped sapphire) [15][16][17][18][19][20], alexandrite [15,16,19,46,47], Cr:LiSAF [15,16,19,48,49], Cr:YAG, or Nd 3+ :YAG [15,16,19,21,50].…”

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.

“…This probe, covering a temperature range from −40 • C to 850 • C (due to technical reasons of testing aperture, a maximum temperature of 850 • C can be achieved), utilizes a ruby crystal and two optical fibers connected to an electronic unit for signal measurement and data processing (Figure 1). The presented paper presents a sensor system exploiting the luminescent properties of a ruby crystal and construction of the probe and the principle of black body radiation [5,14]. A related review article [15] and an article presenting the results of presented high-temperature sensor solution [16,17] were published earlier.…”

This paper presents the construction of an innovative high-temperature sensor based on the optical principle. The sensor is designed especially for the measurement of exhaust gases with a temperature range of up to +850 °C. The methodology is based on two principles-luminescence and dark body radiation. The core of this study is the description of sensing element construction together with electronics and the system of photodiode dark current compensation. An advantage of this optical-based system is its immunity to strong magnetic fields. This study also discusses results achieved and further steps. The solution is covered by a European Patent.
