| Zusammenfassung: | A sapphire fiber bragg grating high-temperature sensor comprises a protective shell, a fiber bragg grating and a fiber bragg grating sensor body, the substrate material is arranged in the protective shell and is fixed on the protective shell; the at least one sapphire fiber bragg grating is adhered to the substrate material through high-temperature glue, and one end of the sapphire fiber bragg grating is connected with a transmission optical fiber; and one end of the transmission optical fiber is connected to the sapphire fiber bragg grating, and the other end of the transmission optical fiberpenetrates out of the protective shell and is connected to an optical fiber bragg grating wavelength detector. The sapphire fiber bragg grating is connected with the fiber bragg grating wavelength detector through the transmission optical fiber, and the fiber bragg grating wavelength detector senses the temperature of the environment where the sapphire fiber bragg grating is located by measuringthe wavelength of the sapp |
