OPTICAL-ELECTRONIC SYSTEM OF HIGH SPATIAL RESOLUTION WHEN OBSERVING REMOTE OBJECTS
(pp. 4-13)

Abstract. Schematic solutions of an optoelectronic system for obtaining high spatial resolution when observing remote objects are studied, which allow obtaining high resolution of objects in the volume of the observed space, providing high accuracy in determining the coordinates and geometric features of objects in three-dimensional space. A hybrid system is considered for simultaneous registration of the entire set of rays from observed objects in a full solid angle by a high-resolution optical system together with a system for registering sets of different sets of ray directions from objects in the same observed space, which makes it possible to form a set of narrow layers of the observed space in range. To further improve the accuracy of obtaining coordinate and non-coordinate information of the observed objects, the images of narrow layers of space are expanded to the resolution of the first optical registration system by weighted substitution of the detail filters of the discrete wavelet transform. Integration in different digital information ranges is achieved by decomposing the image of the first digital source and each of the set of images of the second digital source into low-frequency and high-frequency components, separate processing of image components based on the principle of weighted summation for each pixel, and the formation of the resulting image. Computational experiments have been carried out showing the effectiveness of the proposed circuit solutions in determining the parameters of objects of interest.

Keywords: high spatial resolution, optoelectronic system, image multiplexing, continuous wavelet transform, direct discrete wavelet transform, inverse discrete wavelet transform.
