Planar laser induced fluorescence PLIF technique is to use laser induced part under test or the atomic resonance transition to detect them in a particular quantum state inhabit density keen skills.Because it has a high standard of light intensity and can be measured out especially important and lively trace components, such as: & 3, 3 / - /, etc., K, in the recent 20 years) skills by people as soon as possible.Late, K) is the growth of propulsion by single point measurement techniques, but most extinguishing system constitute a turbulent flame, is growing by two-dimensional measurement techniques, using single laser pulse encourage fluorescence to record the transient flow field and flame layout, has always been a sign of by people.Planar laser induced fluorescence PLIF technique supplies the possibility of a complete it.JK, for nearly a decade) skill obtained the high growth, giving people the supply from the qualitative to the quantitative very fruitful information, has demonstrated the single laser pulse, non-invasive measurement of concentration, temperature, speed, pressure of identity such as 3 D scattered image N EO L P, and the measured flame layout elucidates the burning effect N D P.With usual schlieren and shadow technique to obtain the three-dimensional image of analogy, JK,) can represent complex flow field, determine composition characteristics and supply space distribute information, to the response stream is effective, which can determine the three dimensional flow field layout.Relative Rayleigh scattering and Raman scattering, it's a standard lamp, high strength of several orders of magnitude, and can monitor several flow field parameters at the same time, so have particularly attractive.
We sichuan branch optical precision machinery co., LTD., is to do the schlieren apparatus, planar laser induced fluorescence PLIF, photonic doppler velocimeter instrument technology, such as our telephone number: 0816-6204826
