Abstract
Due to the opacity of most granular materials, it is often desirable to have three dimensional (3D) particle tracking techniques beyond optical imaging to explore granular dynamics. Using inertial measurement units (IMU) embedded in a projectile, we obtain the trajectory of projectile impacting on a granular medium under microgravity using tri-axial acceleration and angular velocity data. In addition to the standard algorithm for reconstruction, we emphasize solutions to various sources of error to determine projectile trajectory accurately.

Kai Huang
Dr. habil. Kai Huang received his BS in Electronic Engineering (2000) and his PhD in Physical Acoustics (2006) from Nanjing University. He did postdoctoral training (2006-2009) at Max-Planck Institute for Dynamics and Self-organization. Since 2009, he started to build a research group at University of Bayreuth in Bavaria and to teach physics courses at both undergraduate and graduate levels. In 2014, he got his 'Habilitation' in physics, a scientific and pedagogic qualification for professors in Germany. From 2015 to 2019, he continued to work at University of Bayreuth as a ‘Privatdozent’. He is interested in understanding, predicting and eventually controlling the collective behavior of sand grains (i.e., granular materials) by means of lab experiments and computer simulations, in order to shed light on widespread applications such as space exploration, powder based additive manufacturing (3D printing), landslide and earthquake triggering, dune migration and transport. He is also interested in the acoustical design of opera theatres (e.g. the Bayreuth Festspielhaus of Richard Wagner), partly as a consequence of his lecture on acoustics.
