Abstract
An effective and universally useful means of adjustment in the realm of precision engineering and microoptics becomes possible with the realization of a new drive. In contrast to traditional adjustment methods, the mechanical component will be situated in its final position before the adjustment process starts. Specific mechanical impulses (momenta) generated by a striking mechanism are transmitted to the mechanical component or its housing (carrier). This results in minute linear or fine angular motions. Prototypes of the electromechanical striking mechanism have been researched and developed. The arrangements make possible the adjustment of mirror, of fibre to fibre or of fibre to opto-electronic sensors. The measuring system with PC-based algorithm allows fast and exact positioning of these components.
