After the introduction of fundamental principles of Laser Induced Fluorescence（LIF）measurement technique,the progress of the key elements of LIF technique,including laser,fluorescence tracer and the camera is reviewed according to temporal and spatial resolution.Then the application of LIF in the field of liquid mixing and mixing-sensitive reactive flow is summarized.The trends of LIF measurement technique are also pointed out.How to choose the right high-speed camera in accord with the laser is the main factor that determines the temporal and the spatial resolution of LIF measurement technique in the study of mixing.In the meantime,the application of LIF in the RD of industrial processes will depend on how to achieve high-precision test with the miniature and low-cost LIF experimental system.
