Gallium arsenide optical fiber temperature sensor is an optical fiber temperature sensor made of gallium arsenide as a temperature sensing substance. The crystal and quartz glass are encapsulated by using the temperature-related characteristics of the optical band gap change of gallium arsenide semiconductor material, which uses light as the medium and quartz glass fiber as the conduction medium. The sensor has no conductor structure, complete immunity to electromagnetic interference, good repeatability, high precision, fast response and long life. It can be used in areas with strict requirements for life and anti-interference, such as RFI, EMI,NMR,RF, microwave, ultra-high voltage equipment and other environments.
The GaAS optical fiber temperature sensor is based on the optical properties of GaAs semiconductor materials, and its core is the principle that the absorption characteristics of GaAs crystals for specific wavelengths of light change with temperature. When the light source emits multi-wavelength light incident on the gallium arsenide crystal, the crystal absorbs different wavelengths of light at different temperatures, and the unabsorbed wavelengths of light will be reflected back to the device. By analyzing the reflection spectrum, the temperature parameters at the probe can be calculated. This measurement method based on spectral absorption changes avoids the need for field calibration and improves versatility and accuracy.
