Abstract: Improved method of surface wave edge detection is developed in the present work. This studying is devoted to the problem of wind-wave interaction in the boundary layer atmospheric - ocean system. Method bases on laser sheet illumination, high rate video taking, and novel algorithms of image analysis. It allows obtaining surface profile on the frames with high accuracy and spatial resolution, also for the case of intensive wave breaking with spray of droplets generation and foam on the crests. The mean wave number spectra of the high-frequency (small scale) part of surface roughness were calculated from the ensemble of wave profiles. This part is determined by breaking events. These results add the spectra of low-frequency part of surface waves obtained by system of string wave gauges.
