The complex of optical devices for remote sensing of sea surface waves for wide diapason of wavelength from centimeters to meters in real time was created. The methods for retrieval of space - time spectra from daylight imagery of sea surface based on twoscale approach of the waved surface was developed. The method for measuring of long energy surface wave's elevation using spectra of shortscale surface waves images was proposed and experimentally tested.
The space - time optical images of capillary waves using artificial diffuse illumination of water surface was derived in water tank with spatial and time resolution 0.3 mm and 300 Hz accordingly. The software for processing of capillary wave's images was developed.
Keywords: optics of ocean, sea waves, spectral analysis, image processing, remote sensing, capillary waves
