Abstract

The invention provides a method, a device, a storage medium and an electronic device for determining focus deviation. The method comprises the following steps: recording Raman spectral data accumulated and collected by a spectrometer sensor of a Raman detecting device at every fixed time intervals in a process that a Raman detecting device emits laser light and performs Raman spectroscopy collection, or recording Raman spectral data accumulated and collected by the spectrometer sensor of the Raman detecting device for one time, when the luminance value of the collected Raman spectrum is increased by a fixed value; extracting peak information of the Raman spectral data recorded each time; determining growth rate from each peak of nth recorded Raman spectral data to n+1th recorded Raman spectral data, according to nth recorded peak information to n+1th recorded peak information; determining whether growth rate of each peak of nth recording is identical; determining the laser light emitted by the Raman detecting device is out of focus, if the growth rate of each peak of nth recording is not identical.

Description

technical field [0001] The present disclosure relates to the field of substance detection, and in particular to a method, device, storage medium and electronic equipment for judging focus deviation. Background technique [0002] Raman detection equipment uses Raman scattering to detect the composition of substances. It is currently used in many fields, including professional oil exploration, drug detection, common security inspections in life, anti-drug and other scenarios. At the same time, with the Raman detection The cost of equipment continues to drop, and there are more applications in the civilian market, such as pesticide detection, genuine and counterfeit detection, etc. [0003] The current Raman detection equipment usually adopts non-contact detection, and it is necessary to manually focus the laser on the object to be tested. However, if the human eye directly looks at the laser focus, it is inevitable that the laser focus will deviate and even be aimed at other ...
