You probably don't know what planar laser induced fluorescence PLIF is, but you have to understand to the planar laser induced fluorescence PLIF technique application range, maybe you will get well with in your life.Burned one of the first branch of flow field in laser diagnosis skills, planar laser induced fluorescence PLIF skills can implement burning of two-dimensional visual measurement of flow field parameters, get rich and intuitive information, is a strong burning flow field confirmed.Based on the theory of fluorescence spectrum analysis, the need to go through 2 d fluorescence intensity distribution to obtain the required components concentration or FenShaoChang temperature information, it is necessary to eliminate the influence of fluorescence signal of laser intensity and spread, thus, precise encourage laser light intensity distribution is very important.Now, in PLIF trials, generally USES the cylindrical lens group will encourage laser plastic sheet beam, but I don't do special smooth processing.In order to satisfied the quantitative measurement of needs, often set refer to light our way in the test system, monitoring and encourage the laser light intensity distribution.Detailed approach is to encourage light gives off a bunch of monitoring of the laser light path, the incident to some kind of fluorescent material filled with cavity is indoor, and camera monitoring the corresponding fluorescence intensity distribution, then according to the calculated contact laser intensity of fluorescence intensity of laser light intensity distribution.This way is in the test system attached to a set of PLIF diagnose system, not only make the system become more valuable, also increased the complexity of the diagnosis system together.If pass beam smooth advance, will encourage laser cosmetic to evenly spread sheet beam intensity, there is no doubt that can be useful in simplifying test progress test precision of the system.In college physics experiment are used widely, maybe you don't know what planar laser induced fluorescence PLIF technology use how much, but now you know.Please remember planar laser induced fluorescence PLIF technique is a new technology of our company, you want to deep understanding to our company!Our company main products are schlieren apparatus, photonic doppler velocimeter, planar laser induced fluorescence PLIF technique, etc.Contact our telephone: 0816-6204826 |
