Abstract

The adaptive optical system serves to correct dynamic image defects, particularly those caused by atmospheric disturbances, and includes a correcting mirror 6 having a controllably deformable surface, an opto-electrical sensor 1 within an image plane of the system and, connected thereto, a control unit 5 for the correcting mirror 6. The sensor 1 is in the form of an image definition sensor having high local resolution with which spatial and temporal variations of the image are picked up in the form of definition signals. Control signals for actuating the correcting mirror 6 are then formed from the definition signals.
