The invention discloses a method and a device for quickly detecting Raman spectrum signals. The method comprises steps as follows: a detection device acquires light signals of samples after receiving a quick detection mode entry instruction, calculates corresponding Raman spectrum signals in real time, calculates the signal-to-noise ratios of the Raman spectrum signals in real time, stops acquisition after judging that the signal-to-noise ratios of the Raman spectrum signals are larger than a signal-to-noise ratio threshold and recognizes the acquired Raman spectrum signals. With the adoption of the method and the device, the average sampling duration of a Raman spectrum signal detector can be shortened by 40%, the required detection accuracy can be guaranteed while the detection speed is greatly increased, the method and the device are particularly applicable to detection of scenes which have single targets and need quick detection, and the detection efficiency of the Raman spectrum signal detector can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of Raman spectrum signal detection, in particular to a method and device for rapidly detecting Raman spectrum signals. Background technique [0002] When the existing Raman spectroscopic signal detector collects the optical signal of the sample, the collection time for different samples is the same, which is a preset fixed time length, such as 1 second or 5 seconds and so on. In the scenario where the detection target is single (for example, only one kind of dangerous goods needs to be detected) and rapid detection is required, the existing detectors cannot meet the usage requirements. In scenarios requiring fast detection, it is necessary to further speed up the time of the detection process. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method and device for rapidly detecting Raman spectrum signals. [0004] The invention provides a ...
