A mathematical model of the brightness structure of an ensemble of small-sized distant light objects in the plane of a photodetector is presented. The structure and principles of construction of optoelectronic systems for registration of distant and small-sized light objects are considered. A method for constructing of algorithms for determining the parameters of an ensemble of objects of different distances, obtained by an optoelectronic system with a digital camera of the light field, taking into account its characteristic features, is developed. A special experimental stand for the study of objects in distant conditions based on a telescopic system and a digital registrator is presented. The principal possibility of creating a light field correlator is shown. A number of algorithms and functions are described, as well as their capabilities to accurately measure the coordinates and parameters of small-sized light objects. The advantages and disadvantages of algorithms based on the continuous wavelet transform are investigated. A comparative analysis of the accuracy of determining the coordinates, dimensions, and features of small-sized objects by various algorithms is presented. It is shown, that the accuracy of determining the coordinates and parameters of small-sized remote objects by digital cameras of the light field is several times higher than by traditional digital cameras.
