    摘要： Embodiments of the present invention provide gem identification method and apparatus. The method comprises the steps: (a) placing a sample to be detected over a light transmission hole formed on a carrying surface of an object table and emitting, by an optical probe disposed below the carrying surface, an exciting light onto the sample through the light transmission hole and then collecting a Raman scattered light from the sample by the optical probe; (b) acquiring a Raman spectrogram of the sample from the collected Raman scattered light from the sample; and (c) comparing the Raman spectrogram with a reference Raman spectrogram library for gems to identify the sample. The method and apparatus may achieve effective, convenient and accurate inspections of the gems.

    摘要： An embodiment of the present invention provides a Raman spectroscopic detection method for detecting a sample in a vessel, comprising the steps of: (a) measuring a Raman spectrum of the vessel to obtain a first Raman spectroscopic signal; (b) measuring a Raman spectrum of the sample through the vessel to obtain a second Raman spectroscopic signal; (c) removing an interference caused by the Raman spectrum of the vessel from the second Raman spectroscopic signal on basis of the first Raman spectroscopic signal to obtain a third Raman spectroscopic signal of the sample itself; and (d) identifying the sample on basis of the third Raman spectroscopic signal. By means of the above method, the Raman spectrum of the sample in the vessel may be detected correctly so as to identify the sample to be detected efficiently.

    摘要： Embodiments of the present invention provide a Raman spectroscopic inspection method, comprising the steps of: measuring a Raman spectrum of an object to be inspected successively to collect a plurality of Raman spectroscopic signals; superposing the plurality of Raman spectroscopic signals to form a superposition signal; filtering out a florescence interfering signal from the superposition signal; and identifying the object to be inspected on basis of the superposition signal from which the florescence interfering signal has been filtered out. By means of the above method, a desired Raman spectroscopic signal may be acquired by removing the interference caused by a florescence signal from a Raman spectroscopic inspection signal of the object. It may inspect correctly the characteristics of the Raman spectrum of the object so as to identify the object effectively.
