Abstract

Conventionally, particle image velocimetry techniques utilize a laser light sheet oriented perpendicular to the viewing direction to illuminate tracer particles. In this SPIE proceedings paper, initial results are presented based upon illuminating the region of interest with partially coherent light from behind the particle and viewing the forward scattered diffraction pattern using video microscopy with a CCD array. There are several distinct advantages to this arrangement, including: easily identified particle centroids and the possibility of simultaneously obtaining the fluid velocity in different planes perpendicular to the viewing direction without moving the imaging system or illumination source. This technique will be referred to as Coherent Forward Scattering Particle Image Velocimetry.
