title: Analysis of electrohydrodynamic jetting behaviors using three-dimensional shadowgraphic tomography.
abstract: Electrohydrodynamic jetting behaviors of liquid menisci were analyzed experimentally by three-dimensional optical shadowgraphic tomography. The tomographic algorithm was developed after a series of multiplicative algebraic reconstruction techniques updated the object's intensities by using a cubic cosine basis function to determine the weighting coefficients of the projection matrix. The algorithm was evaluated initially by using a synthesized three-dimensional droplet phantom. Three-dimensional reconstructions of several jetting modes were built based on three images of projection data captured by three high-speed cameras, which were positioned at an offset angle of 45° relative to one another.
