Abstract
Apparatus for spatially resolved temperature measurement, comprising at least one optical fiber (4) for spatially resolved temperature measurement, at least one laser light source (1), the light (11) from which can be coupled into the optical fiber (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 fiber (4) can be coupled out of the optical fiber (4) and detected, modulator means (2) permitting the modulation of the light (11) that is to be coupled into the optical fiber (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 fiber (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).
