Abstract
A method and an apparatus of measuring a position of a particle in a flow are disclosed. An embodiment of the method comprises temporally modulating and spatially pattering an illumination beam propagating along a first dimension, passing a particle across the modulated illumination beam, detecting a temporal profile of scattered light produced by the particle's passing through the modulated illumination beam, and determining the position of the particle based, in part, on the temporal profile of the detected scattered light.
