Abstract
Advances in the last 10 years in image acquisition sensors, high quality illumination sources and cluster parallel processing have allowed us to develop and advance a number of digital techniques that enable the measurement of instantaneous three component fluid velocity vector fields in a three-dimensional volume. This paper gives a brief overview of two methods based on Incoherent Imaging, namely Tomographic PIV (TPIV) and Light-field PIV (LFPIV) and one method based on Coherent Imaging, namely Digital Holographic PIV (DHPIV). TPIV has wide acceptance in Experimental Fluid Mechanics laboratories despite its demonstrated limitations in high-fidelity turbulence measurements, whereas LFPIV and DHPIV are in many ways conceptually simpler and their limitation are current sensor technology, which with time should become less of an obstacle to their usage.
