Description

technical field [0001] The invention relates to the technical field of detection, in particular to a fluorescent substance detection device and method. Background technique [0002] Fluorescence is a photoluminescent cold luminescence phenomenon. Fluorescent substances refer to the fact that electrons in the substance can enter the excited state under the excitation of light of a certain wavelength and intensity, and then transition back to the ground state to produce fluorescence of a certain wavelength. substance. Among them, oil stains in water contain a variety of fluorescent substances, such as monocyclic and polycyclic aromatic hydrocarbons. These compounds will emit fluorescence at a specific wavelength under the irradiation of laser light of appropriate wavelength and intensity. [0003] At present, there are many detection instruments or devices for detecting oil in water based on the above principles, including contact and non-contact oil in water detection device...
