Time evolution of the density field of a micro-explosion is captured using the high speed BOS technique. The flow structure near the core is captured due to the shorter exposure of the camera which was not possible in the earlier efforts that used discrete single shot cameras. However, the lower spatial resolution of the high speed camera was unable to capture the finer details of the turbulent core. The study shows the usefulness of capturing the time evolution of the density field. Such data can be enormous help in validating CFD models.
