Abstract
A wavelength domain scheme was proposed based on hybrid Sagnac interferometer. The temperature was measured by detecting the extremal wavelength of the interference spectrum, an experimental sensor was setup to verify the effectiveness and accuracy of the scheme. The wavelength variation with temperature was 1.36nm/°C and linear equation was obtained.
