Method and device for contactless temperature monitoring and temperature adjustment
First Claim
1. A method for determining the temperature of a biological sample, the method comprising:
- a) directing a probing light beam onto the sample, at least two partial beams of the probing light beam passing through at least two separate long path lengths in the sample, the at least two partial beams reflected or backscattered from at least two different depths in the sample;
b) employing an interferometric device and one beam of the probing light beam as a reference light beam to produce an interference pattern in an analytical unit;
c) directing the interference pattern to an evaluating unit;
d) evaluating the interference pattern in the evaluating unit by comparing a signal intensity of the reflected or backscattered partial beams with an optical path length in the evaluating unit to determine a temperature displacement and a sample temperature from the temperature displacement of the signal intensity.

Abstract
A method and device for determining the temperature of a sample, wherein a probing light beam is directed onto the sample whereby at least two partial beams of the probing light pass through paths of different lengths inside the sample by backscattering or reflecting the beams from at least two different depths in the sample, returning the partial beams to an analysis unit, and producing an interference pattern in the analysis unit by means of an interferometric device which uses one light beam as a reference for evaluating the interference pattern in an evaluating unit, wherein the signal intensity of the partial beam is determined counter to the optical path and the temperature displacement and temperature of the sample are determined by the temperature adjustment of the signal intensity.
