摘要：Disclosed is a method for the non-invasive optic determination of the

temperature of a medium, preferably a water-containing medium, wherein the medium to

be analyzed is illuminated by infrared and/or visible light in the region of an absorptionline, the position of which depends on the temperature of the medium, and whereinabsorption of the light in the region of the absorption line is measured and the

temperature is determined from said measurement by comparison with calibration data.Said method is characterized in that the medium is illuminated with at least two discretelight wavelengths (λ, λ), which are in the region of the absorption line (B) on differentsides of the absorption maximum, that at least one measured value (ΔA/Δλ) dependenton temperature is determined from the relationship of these two determined absorptionvalues to one another, and that the temperature is determined from said measured valueby comparison with the previously recorded calibration data.
