  • 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.
