Laser Induced Fluorescence (LIF), belongs to spectroscopic diagnose technology, is a new method of flow visualization and measurement which obtain real-time two-dimension or three-dimension spatial distribution information via non-intervention, and undertakes quantitative measurement of concentration field, temperature field, pressure field and velocity field.
Know-why: According to the material molecular absorption spectrum and fluorescence spectrum energy level transition mechanism, choose a suitable laser wavelength through the detection area, under specific wavelength laser irradiation, the substance with ability of absorb photon transition to the unstable upper state, and then in a certain period back to the ground state. During this process, molecules release energy via spontaneous radiation, thereby fluoresce.
Laser induced fluorescence spectrum obtained through the detector detecting laser induced fluorescence intensity and distribution. Sample particles types are detected through fluorescence distribution analysis, particle concentration and temperature are obtained from fluorescence strength analysis, and particle space concentration and temperature distribution are detected by its spatial resolution analysis.
At same time, complex flow field visualization and intuitive analysis can be realized by using CCD camera or other image acquisition tool to record flow fluorescent images. |
