Sumario:[EN] This work analyzes the free surface of a hydraulic jump with a Froude number of 7.2. The turbulence of the flow requires instrumentation with high sampling rates to capture the rapid fluctuations of the free surface; so, an Intel® RealSense D435if depth camera is used to capture the surface in three dimensions with good spatial and temporal resolution in a non-intrusive way. The results of the aerated free surface obtained with the depth camera are compared with the values measured by a conductivity probe with a 0.4 mm thick electrode, built at the Hydraulics Laboratory of the Universidad Politécnica de Cartagena. The analysis indicates that the non-intrusive camera detects the mean free surface associated with air fractions between 50% and 90%.
