Journal ArticleDOI
Concentration profiles of dry powders in a gravity conveyor using an electrodynamic tomography system
TL;DR: In this article, a tomographic system using an array of electrodynamic sensors is presented, where sensitivity maps are derived for individual sensors and then used by a back-projection algorithm to calculate concentration profiles from measured sensor values.
Journal ArticleDOI
Velocity and mass flow rate profiles of dry powders in a gravity drop conveyor using an electrodynamic tomography system
TL;DR: In this article, the authors describe measurements made on a gravity drop conveyor using two arrays of axially spaced electrodynamic sensors to measure axial velocities close to the wall of the conveyor and velocity profiles both of flowing sand and of plastic beads.
Journal ArticleDOI
Optical sensor configurations for process tomography
TL;DR: An investigation into the optimum design of optical fibre sensing arrays to be incorporated in an optical tomographic measurement system for on-line monitoring of particles and droplets and a hybrid reconstruction algorithm is implemented to improve image quality.
Optical Fibres For Process Tomography: A Design Study
TL;DR: In this article, a model of optical fiber sensing arrays aimed at optimising the design of the tomography system being built by the authors is presented. But the authors do not consider optical attenuation due to material with differing optical densities.
