Abstract

A method for actuating an acoustooptical element includes generating an actuation signal by a direct digital synthesis (DDS) method using a signal value sequence made up of at least two frequency components. A signal generator for actuating an acoustooptical element is configured to perform the method. An arrangement includes the signal generator and the acoustooptical element. A microscope includes the arrangement.
