Abstract

The spatio-temporal distribution and evolution of wave fields is measured by the acquisition of optical video image sequences. An experiment at the wind wave flume of the University of Hamburg was performed to measure small-scale processes at the water surface. From the image sequences, image spectra are calculated by a 3D Fast Fourier Transformation. This spectral description is limited to stationary and homogeneous wave fields and therefore other techniques which are designed for local scales are applied.
