Leveraging time resolved Shake-the-Box to analyze and optimize multi-pulse STB experiments

Abstract

Evaluation of Shake-the-Box (STB) [1] experiments require careful adjustment of parameters in the STB processing chain. This can be challenging for complex measurement setups, especially in multi-pulse STB applications. Apart from the need for optimal parametrization there is also an interest in understanding the tradeoffs undertaken with a specific parameterization and to diagnose possible issues in the measurement setup. Multi-pulse experiments (MP-STB) [2] can pose a bigger challenge for correct parametrization than the time resolved variant (TR-STB), as short tracks are naturally less robust with respect to ghost rejection. A particle that is tracked for hundreds of steps in a time resolved setup is almost certainly a correct one. Based on real experimental data [3], consisting of a challenging MP-STB setup utilizing polarization based image separation, we present an approach to leverage the strength of TR-STB in the analysis and optimization of MP-STB experiments.
