Development of light-field motion tracking technology for use in laboratory studies of planet formation

Abstract
Modelling of planet formation requires empirical data on the collisions involved in the earliest stages of the process. Laboratory-based studies are required to gain this data by colliding dusty, icy particles in conditions analogous to those found in protoplanetary disks. Having technology to capture experimental footage and extract the three-dimensional motions of ensembles of particles is crucial to generating accurate collisional data within a practical timeframe. The cost of microgravity-based experiments drives a need to minimize the form-factor of such an imaging system leading this work to use light-field techniques to provide the depth element of tracking from a single camera. This work focused on the development of software to be used to perform light-field based, three-dimensional tracking and its application to real-time analysis of mm-scale particle collisions.

Ellen Daly is a PhD research student currently studying at the Open University in the UK. She previously obtained an MEng Mechanical Engineering from the University of Warwick including two years of involvement with the Warwick University Satellite Team (WUSAT). Her current research involves the analysis of collisions analogous with those at the earliest stages of planet formation with a particular focus on the development of a light-field based imaging system to perform automated tracking of icy-particles.
