Abstract: An electromagnetic drive system drives the oscillating secondary mirror or wobble mirror of a reflecting telescope. The driving force of the drive system is directly proportional to the current and the drive system is digitally controllable. By incorporating a tachometer generator and a contactless operating position measuring unit, it is possible to select such function curves for the leading and trailing edges of the wobble function which will permit a jolt-free drive of the mirror.
