Abstract

A projector having at least one laser diode which is designed to emit light, having a laser control device which is designed to control the at least one laser diode, having a first controllable resonant mirror which is designed to reflect the light that is emitted by the laser diode, and having a control device which is designed to control the orientation of the first controllable resonant mirror. The control device is further designed to reduce the power supply to the laser diode and to the laser control device in a first configuration of a power-saving mode of the projector, and to further control the orientation of the first controllable resonant mirror at a resonant frequency of the first controllable resonant mirror. Moreover, a corresponding method is described.
