Abstract
A particle monitoring system may include a flow passage, a particle imager to image a targeted particle within the flow passage, electrodes supported proximate the flow passage, a power source connected to the electrodes and a controller to cause the power source to charge to electrodes so as to (1) apply an electric field balanced with respect to gravity so as to hold, levitate and rotate a targeted particle within the flow passage during imaging and (2) release the targeted particle following the imaging.
