FIELD: optic engineering.
SUBSTANCE: telescope active adaptive electro-optic control system device has main and secondary mirrors; wavefront general decline two-coordinate mirror connected with the first two mirrors; deformed mirror corrector; beam splitter, wavefront detector which has input connected with beam splitter; wavefront decline estimation unit, device for estimating (filtering) inclinations of wavefront, phase restorer, optimal control signal former. Reference point source forming unit is introduced into the device additionally which source has output being optically connected with wavefront common inclination two-coordinate mirror and with secondary and main mirrors of telescope.
EFFECT: increased isoplanatic angle of telescope's field of view; improved precision of correction of wavefront distortions.
