Method for the correction of the wave surface of an optical beam by means of a deformable and mirror used in this method

摘要

The electrically activated deformable mirror (1) corrects optical surface wave reflections. The mirror has a series of electrical actuators (5) which push the rear of the mirror in specific areas. The electrical current applied to the actuators follows the natural vibration mode of the mirror, so as to provide the required mirror correction.
