摘要： A micro-mirror system having a micro-mirror actuator, a sensor for detecting the position of the micro-mirror actuator, a light module having at least one light source and an associated control system via which a light intensity of the light source is controllable, and an evaluation and control unit which is designed to control the micro-mirror actuator as a function of an output signal of the sensor. The system provides that the evaluation and control unit includes a compensation routine in which an offset voltage of the output signal of the sensor is settable as a function of the light intensity of the light source to be expected at the point in time that the micro-mirror actuator is activated.
