The report consists of three parts: (1) Methods and means for observing and 3D imaging of underwater static and dynamic objects (e.g., mines and living beings). The methods are based on optical refraction, diffraction, and the Talbot effect on the water surface disturbed by ultrasound waves reflected or passed by the object. An algorithm to calculate the shape of disturbed water surface has been developed. It was also used for realization of an ultrasound holography system. Computer-aided cross-section recovery of 3D image of a submerged object is described. The Talbot effect and the algorithm developed are shown to be useful for measure of the shape, thickness and velocity of oil spreading on the water surface; investigation of drops creation and measuring their forms. (2) Observation and 3D imaging of static and dynamic objects inside or behind optically opaque solid media using a microwave holographic movie camera recording the radiation passed through the object. (3) The design of the agreement for the feasibility study and technical development of mobile facility for detection of landmines or other objects inside or behind an opaque obstruction using the radiation reflected from the object.
