Using a light transmission technique a new experimental setup allows to study the spatio-temporal behavior of Faraday surface waves in a fully quantitative manner. As an example, the bifurcation of a doubly-hexagonal superstructure out of a simple hexagonal pattern is presented. It is demonstrated that both amplitude and phase information can be obtained. The empirical results are found to be in agreement with theoretical considerations based on resonance arguments and the amplitude equation approach.
