Abstract

Abstract Translated from German ls Antriebssystem für den oszillierenden Sekundärspiegel eines Spiegelteleskops (Wobbelspiegel) wird ein elektro-magnetisches Antriebssystem verwendet, dessen Antriebskraft direkt proportional dem Strom ist und das digital ansteuerbar ist. In Kombination mit einem Tachogenerator und einem berührungslos arbeitenden Wegmeßsystem ist es möglich, für die An- und Abstiegsflanken der Wobbelfunktion solche Funktionskurven zu wählen, die ein ruckfreies Anfahren des Spiegels ermöglichen. As a drive system for the oscillating secondary mirror of a mirror telescope (wobble mirror), an electro-magnetic drive system is used, the drive force of which is directly proportional to the current and which can be controlled digitally. In combination with a tachometer generator and a non-contact measuring system, it is possible to select such function curves for the rising and falling edges of the wobble function that enable the mirror to be started up smoothly.
