PROBLEM TO BE SOLVED: To provide a dynamic manipulation and adjusting method for a module or component in an optical system. SOLUTION: Module or component, for example a lens, of the optical system is shifted by at least two actuators having sensors to decide the relative path displacement, and the position of the component is decided by at least two sensors, and these actuators and sensors make communication via a control loop. A mechanical impulse is given to the component by the actuators, where the timing is changed any as desired. The movement of each actuator is executed by a temporally varying velocity profile ordered as a function of the position (Sn <actual> ) decided concerning the set position (Ssetpoint ) of the component, and thereafter the position (Sn <actual> ) is redecided. This cycle of steps is repeated until the component 2 reaches the desired position (Ssetpoint ).
