Abstract
The paper is devoted to the development of optical methods for investigations of surface waves. The no coherent optical multichannel spectrum analyzer for space - time (3D) spectral measurements of sea surface waves in real time is developed. The model of space - time (3D) spectra of sea surface short scale wave's optical image taking into account elevation of the long energy surface waves and comparative measurements of optical image spectra and Doppler spectra of X-band scatterometer are presented. A method for retrieval of absolute value of long wave elevations from optical image spectra is proposed. The high-speed optical system based on linear array of CCD photodiodes for registration space - time images of capillary waves is created. The data on free and bounded capillary waves derived with this system in laboratory tank with artificial diffuse illumination is presented.
