FIELD: optics.
SUBSTANCE: device contains device for generating a reference point source, two-coordinate total wave angle mirror, secondary and main mirrors, which are optically connected with the device for generating a reference point source, as well as with the deformable mirror corrector, the beam splitter, and the focal plane of the image, as well as a wavefront sensor, the input of which is connected to the beam splitter, wave angle evaluation (filtration) device, phase restorer, and devices generating optimum control signals. Additionally, a device for adaptation to the change of wave angle properties is introduced, the input of which is connected to the output of the wavefront sensor, and the output of which is connected to the input of the wave angle evaluation (filtration) device.
EFFECT: increase in wavefront distortion correction accuracy and obtaining of object image quality that is best possible in current observation conditions.
