Abstract
A method for controlling a drive apparatus () of a micro-oscillation mirror (), a control device () and a deflector mirror apparatus () are described. In the method, at least one actuation signal () is generated, and the drive apparatus () is actuated therewith in such a way that it drives the micro-oscillation mirror () in an oscillating fashion, At least one position signal () which characterizes the deflection () of the micro-oscillation mirror () is sensed. The at least one actuation signal () is closed-loop controlled on the basis of the at least one position signal () in such a way that the micro-oscillation mirror () is driven at its resonant frequency, The amplitude of the at least one position signal () is continuously compared with at least one threshold value (). At least one time interval () between at least two passes of the at least one position signal () through at least one threshold value () is determined. The at least one actuation signal () is closed-loop controlled on the basis of the at least one time interval ().
