Paper Abstract

The future telescopes indeed for exploring deep space should possess a large-clear-aperture low-weight primary mirror. Optical quality of such a mirror will apparently be non-ideal and, therefore, such a telescope will have to be supplied with a system of image correction. We consider a computer-based telescope comprising its primary mirror (PM) of a non-ideal optical quality, a laser system illuminating the PM to inquire the distortions of the specular surface, secondary optics, CCD matrices, and a computer with a proper software. This telescope allow one, in principle, to obtain images of deep-space objects with a high angular resolution in the time-delayed (rather than real-time) mode because of computer processing of the information. In the paper, we also discuss advantages and disadvantages of the analog (nonlinear optical) and digital (phase-diversity) image correction techniques.
