Abstract
A temperature sensor is provided which comprises a measurement light source for generating measurement light and two optical waveguides. The two optical waveguides are arranged such that they respectively receive a measurement light portion of the measurement light and that the measurement light portions are superimposed after passing through the optical waveguides. Furthermore, the two optical waveguides have an optical property with different temperature dependency.
