Apparatus for spatially resolved temperature measurement, comprising at least one optical fibre (4) for spatially resolved temperature measurement, at least one laser light source (1), the light (11) from which can be coupled into the optical fibre (4), wherein those components (12, 12a, 12b) of the light (11) produced by the laser light source (1) which are scattered back in the optical fibre (4) can be coupled out of the optical fibre (4) and detected, modulator means (2) permitting the modulation of the light (11) that is to be coupled into the optical fibre (4), and also demodulator means (5, 6) which permit a demodulation of those components (12, 12a, 12b) of the light (11) which are coupled out of the optical fibre (4), wherein the demodulator means (5, 6) are designed as optical demodulator means (5, 6) and/or wherein the modulator means (2) are designed as optical modulator means (2). |
