A free-surface synthetic Schlieren technique developed by Moisy et al. (Exp Fluids, 2009) has been implemented in order to measure the surface topography generated by adroplet bouncing on a vibrating fluid bath. This method was used to capture the wave fields of bouncers, walkers, and walkers interacting with boundaries. These wave profiles are compared with existing theoretical models and simulations and will prove valuable in guiding their future development.
