Probe Photometers (go1n 21/85b) Patents (Class 356/953)
  • Patent number: 8107068
    Abstract: The present invention relates to a Raman spectroscopy system that includes a detection center. The detection center includes at least one light source for outputting exciting light which excites a detected object to generate Raman scattered light, and an analysis device for obtaining the Raman spectroscopy of the detected object. The Raman spectroscopy system further includes at least one detection terminal, each of which includes at least one Raman probe that each introduces the exciting light to the detected object, collects the Raman scattered light generated by the detected object, and returns said Raman scattered light to the detection center. The present invention also relates to a method for detecting Raman spectroscopy.

  • Patent number: 7357570
    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.
