Nowadays the domestic space technology has gradually mature, research and development of space flight is the essential technology.Driving skill is the growth of aerospace vehicle is the sticking point of research and development, and is the most important key in driving skills.Planar laser induced fluorescence PLIF were able to get out of the two-dimensional spread information, is an important diagnostic method.From the discussion of three-dimensional laser induce fluorescence technique at home and abroad and using the pause to see, to the use of planar laser induced fluorescence PLIF has increasingly mature, but the PLIF planar laser induced fluorescence detection SNR performance shortage of deep discussion, the planar laser induced fluorescence PLIF using the parameters in the comment debate is also a matter of choice.This paper important discussion OH the base in the Bunsen flame spread of three-dimensional laser induce fluorescence technique, and the detection of the signal to noise ratio.Begin to introduce the topic map inner entourage of and planar laser induced fluorescence, the growth status of PLIF aspects,Later on planar laser induced fluorescence and Bunsen flame OH PLIF process spread of coherent practice stopped exposition;Through a process plan to build system of PLIF, to divide Bunsen flame OH the base to distribute in the cases of stop detection, the theory and practice to stop comparing test results, the results verify the accuracy of OH - PLIF detection;The end detection have differences and differences under the condition of the laser energy detection under the condition of the door wide OH Bunsen flame - PLIF images, on the laser energy and detecting the door to OH PLIF images wide part of the influence of signal-to-noise ratio.Our company mainly research and development of technology, including planar laser induced fluorescence PLIF technique, etc.Technology research and development has been increasing, to mature.If this technology to further understand you, just contact us, our telephone: 0816-6204826
