Experimental acceleration fields are extracted from two subsequent velocity measure- ments using a post-processing technique with high accu- racy, see Jensen and Pedersen (2004). The dynamics of steep irregular waves are often reported from experiments conducted with Laser Doppler methods, which are measuring the velocity/acceleration at a point location.
