Die Eigenschaften des Temperaturmesssystems mit faseroptischen Gittersensoren

The fiber optic grating temperature measurement system is a temperature measurement product developed and produced based on the temperature sensing technology of fiber optic gratings.

Grating is a fiber optic that undergoes special processing to change its refractive index, allowing it to reflect only at specific wavelengths. Auf diese Weise, after a broad-spectrum incident light passes through the fiber optic grating, only the light signal with a very small spectral width that meets the wavelength matching condition is reflected, and the light signals of other wavelengths are transmitted into the next fiber optic grating. When the ambient temperature changes, the center wavelength of the reflected light in the fiber optic grating will also change (desto höher die Temperatur, the greater the wavelength offset). By digitizing and accurately measuring the center wavelength of the reflected light of the grating to be measured, the ambient temperature at the position of the grating can be obtained.
