Fluorescence spectroscopy is a means of irradiating a sample to be measured with a light source of a shorter wavelength (preferably ultraviolet), the sample spontaneously emitting fluorescence of a longer wavelength after conversion by absorption of photons from the light source, and finally determining the substance and content by analysis of the fluorescence intensity and wavelength. Compared with other common absorption or reflection spectrums, the fluorescence spectrum is an emission spectrum, and the signal intensity of the fluorescence spectrum is directly related to the intensity of an incident light source; in the scene of detecting low content of the to-be-detected substances such as tobacco shred essence, the fluorescence spectrum has lower detection limit and lower detection precision.
