The paper is devoted to the development of optical method for investigation of surface waves using RTI images (images in range - time - intensity coordinates) constructed from optical sections of surface. The technique for creating of large scale RTI images of sea surface under grazing angles was developed. The optical system for monitoring of coastal zone and inland waters from a ship or airplane was created. Some examples of large scale RTI images recording from high shore for various wind conditions, sea state are presented.
The underwater processes and wind are displayed on water surface due to its influence on surface roughness. The method for registration of large scale features of near surface wind fields using its manifestations on water surface is presented and method for retrieval of wind speed from optical image of waved water surface is discussed
Keywords: optics of ocean, sea waves, spectral analysis, image processing, remote sensing, gravity - capillary waves
