Structured-Illumination Microscale Particle Image Velocimetry

Abstract

The goal of this one-year effort was to develop a new particle velocimetry method, structured-illumination microscale particle-image velocimetry (SIPIV), that exploits structured-illumination microscopy (SIM) approaches originally developed to optically section biological samples in fluorescence microscopy, i.e., isolate the signal from the focal plane for a sample illuminated over its entire cross-section. We proposed to evaluate the spatial resolution of SIPIV by using SIM to image steady laminar Poiseuille flow seeded with neutrally buoyant particles through a microchannel.
