Research Abstract	In this study, three types of scalar measurement technique have been developed, in order to understand experimentally the scalar mixing in turbulence under mean concentration variation, in particular, diffusivity being much less than kinematic viscosity. Single/two-point measurement reveal the validity of theory for scalar spectrum. Measurement technique using area/line-scan cameras has been developed for investigating macro-/micro-scopic mixing and has been verified by turbulent mixing jet.
