Abstract :
Measuring the spatio-temporal evolution of dynamic phenomena at sub-micron level is non-trivial due to the diffraction limit of optical systems. This paper describes a technique which allows imaging of sub-micron features of fluid-based phenomena, specifically the determination of their velocity and trajectory.
