Abstract
The present disclosure relates to a positioning device for positioning an object in a positioning plane. To minimize the position error (contouring error) in a continuous orbital travel in contrast to two linear adjusters (X and Y) arranged at a right angle to each other, the positioning device includes two rotation drives having different diameters and an object receiver for receiving the object. The object receiver is coupled to a first of the two rotation drives, which in turn is coupled to the second of the two rotating drives so that the object receiver is rotatable about the axes of rotation (A, A) of both rotation drives that are offset in parallel, and is thereby adjustable in the positioning plane. A light processor having such a positioning device, and a method for laser eye surgery using such a light processor are also disclosed.
