With the continuous development of sensing technology, people’s demand for sensor technology is also increasing day by day. Fiber optic sensors that meet the conditions of high sensitivity, low cost, simple preparation process, and good stability are rare. In the process of sensing and detection, sensitivity and stability are the main technical influencing factors, while preparation process and cost are important influencing factors in industrial production. Sensors that combine these advantages are receiving increasing attention and favor.

Fiber optic sensors are sensors that convert the state of the object being measured into measurable optical signals. The application range of fiber optic sensors is very wide, involving almost all important fields of national economy and defense, as well as people’s daily lives, especially for safe and effective use in harsh environments. The working principle of fiber optic sensors is to send the incident light beam from the light source into the modulator through an optical fiber. The interaction between the modulator and the external measured parameters changes the optical properties of the light, such as intensity, wavelength, frequency, chéim, staid polaraithe, srl., becoming the modulated optical signal. It is then sent through the optical fiber to the optoelectronic device and demodulated to obtain the measured parameters.

In the existing technology, there are many methods for temperature detection, and the sensors used mainly include bimetallic temperature sensors, thermistor temperature sensors, and infrared temperature detection devices. These temperature sensors all have different drawbacks, such as bimetallic temperature sensors being sensitive to electromagnetic radiation and not suitable for electromagnetic scenarios; Thermistor temperature sensors require a current source to be loaded during use, which can generate self heating over time. Thermistor temperature sensors are highly sensitive to self heating, causing self heating errors; Infrared temperature detection devices should be vertically incident on the surface of the object being detected during temperature measurement, which is inconvenient to use in narrow spaces.

Fiber optic temperature sensors have a wider range of applications due to their advantages of anti electromagnetic radiation and passive detection. The existing fiber optic temperature sensors can be pre embedded in narrow spaces to achieve temperature measurement. For objects without temperature measuring optical fibers, when temperature measurement is required, the optical fiber temperature sensor can also be pushed into the object through a traction device;

Accurate temperature measurement is crucial in engineering application systems such as aerospace, high-power stable lasers, and high-precision CNC machine tools. Fiber optic temperature sensors are mainly used to detect changes in external environmental temperature. Compared with ordinary electrical sensors, fiber optic sensors have no electromagnetic interference, strong corrosion resistance, easy manufacturing, low cost, freagra tapa, and high detection sensitivity.
