Abstract
An overview is given to the methods of laser spot displacement control for compensation of eye movements during the eye microsurgery operations. Two major techniques were experimentally investigated: (1) with a mirror controlled electro-mechanically, and (2) having acousto-optic Bragg cells with controlled spatial frequency of diffraction grating. In both cases, displacements of 2 mm from the point of sight fixation were realized with an accuracy 0.1 mm and 0.01 mm respectively. Attention is paid to the methods combining TV techniques with spatial coding of light irradiation for reflexes tracking.
