The development of laser technique applied in the field of fuel spray experiment

In this paper,the development of laser measuring technique of fuel spray in recent years is reviewed.The principles,characters and problems of fuel spray of LDV(laser doppler velocimeter),PIV(particle image velocimetry), laser scattering.laser holography,laser flourescence and laser extinction method applied in the field of fuel spray experiment are introduced.Finally,the application perspective of laser measuring technique in the fuel spray is pointed out.
