Buchmann, N. A. and Willert, C. and Soria, J. (2011) Tomographic Particle Image Velocimetry using Pulsed, High Power LED Volume Illumination. 9th International Symposium on Particle Image Velocimetry – PIV’11, 21-23 Jul 2011, Kobe, Japan.

This paper investigates the use of high-power light emitting diode (LED) illumination in Particle Image Velocimetry (PIV) as an alternative to traditional laser-based illumination. The solid-state LED devices can provide averaged radiant power in excess of 10W and by operating the LEDs with short current pulses, considerably higher than in continuous operation, light pulses of sufficient energy suitable for imaging micron-sized particles can be generated. The feasibility of this LED-based illumination for tomographic PIV is demonstrated in this paper by measuring the turbulent velocity field in gridgenerated homogeneous turbulence.
