Stroboscopic \textit{in situ} detection of 2D superfluid dynamics in BECs

Bose-Einstein condensates (BECs) serve as an attractive medium for the study of quantum turbulence. Of particular interest is the ability of a BEC to sustain quantized vortices and solitons, which are central to our understanding of superfluid dynamics. Further studies of such dynamics would be greatly aided by minimally destructive \emph{in situ} detection of these microscopic density features. We demonstrate, discuss, and compare multiple methods of stroboscopic \emph{in situ} detection of 2D vortex distributions and superfluid wave phenomena in single component rubidium-87 BECs.
