<p>Multiphase fields find wide
applications in the fields of combustion, sprays, turbomachinery, heating and
cooling systems, blasts, energetic materials, and several more areas of
engineering interest. As the efficiency and performance of these systems depend
heavily on the underlying multiphase field, studying their intricate structural
features becomes important. The current study follows the development of a
three-dimensional Wide-Angle Relay Plenoptic (WARP) imaging system with two image
quadruplers for the tomographic imaging of multiphase fields. 3D printed
targets were used to simulate both semi-transparent as well as opaque particle
fields to emulate multiphase systems. Tomographic reconstruction of the targets
was performed using the iterative MART reconstruction algorithm in a commercial
image processing software. Reconstructions were performed at different angular
separations between the cameras as well as for varied separation
distance between the object and the imaging system. Quantitative
analysis of the reconstruction quality of the developed system was performed to
study the effectiveness and accuracy of this system in imaging multiphase
fields. The effect of varying different system parameters on reconstruction
quality has been studied to evaluate the best system configuration for imaging
multiphase fields.</p>
