Abstract
The system of optical devices for remote sensing of near surface layer of the ocean is created. The system consists of a set of original linear array of CCD-photodiodes for the recording of range – time – intensity images (RTI images) of sea surface from optical sections of sea surface and incoherent two-dimensional optical spectrum analyzer (TOSA) for the recording of the sea wave spectra by spectral analysis of the sea surface images in real time. Two these RTI images with various directions of observations enable one to receive complete information about kinematics characteristic of various manifestations on the sea surface, including sea surface waves regardless of its dispersion relation, near surface wind flow manifestations on the sea surface, internal waves (IW) manifestations, oil slicks owing to its ability to screen objects according to their velocity. The recording of short wave spectra perform by the optical spectrum analyzer synchronous with the RTI images of sea surface. The examples of investigations of long surface wave field, sea wave spectra and manifestations of wind gusts and IW are presented.
