The application of fiber optic sensors

Fiber optic is widely used in the sensing field due to its small size, light weight, corrosion resistance, and resistance to strong electromagnetic interference. Temperature detection is an important application field of fiber optic sensing technology. Compared with traditional electronic temperature sensors, fiber optic temperature sensors can be more widely used in specific fields such as aerospace, nuclear testing research, biomedicine, etc.

There is a certain correspondence between the fluorescence afterglow characteristics of fluorescent materials and temperature, such as light intensity, duration, wavelength, etc. By using this correspondence, various parameters of the fluorescence afterglow stage of fluorescent materials can be measured, and through certain conversions, corresponding temperature data can be obtained. The fiber optic fluorescence temperature measurement probe is one of the key components of the fiber optic fluorescence thermometer designed based on this principle. The fiber optic temperature sensing probe and demodulation method aim to improve the sensitivity of temperature detection while ensuring that the preparation method of the fiber optic temperature sensing probe is simple and the preparation cost is low.

Temperature detection is a crucial process in many fields of industrial production. Currently, there are various types of temperature measurement instruments used in industrial processes, laboratories, or special industrial environments. Among them, fluorescence fiber temperature sensing technology based on the combination of fluorescence technology and fiber optic sensing technology is the most active field. This technology utilizes the fluorescence decay time and temperature related characteristics of fluorescent materials to detect the temperature of the luminescent area. It has the advantages of high reliability, good insulation performance, resistance to electromagnetic interference, good repeatability, fast response speed, and small volume.

What are the types of fiber optic temperature sensors

Fiber optic temperature sensors mainly include fiber optic Fabry Perot, fiber optic grating, and fiber optic fluorescence sensors. And most of the demodulation systems corresponding to these sensors are also implemented using optical demodulation methods. The demodulation systems of the first two sensors are easily affected by environmental factors due to the use of optical demodulation methods. The demodulation system of the fiber optic fluorescence temperature sensor adopts electrical methods. The fiber optic fluorescence temperature measurement probe is compact, easy to bend, corrosion-resistant, and can be used to measure in various environments. As a probe for various measurement equipment, it can work in environments where existing temperature measurement devices are difficult to work. The implementation method is flexible, fast, and has strong universality.
