Micromechanical component and a method for operating a micromechanical component

A method for operating a micromechanical component having a light window and a mirror element configured to be adjustable with respect to the light window of the micromechanical component from a first position about at least one axis of rotation into at least one second position, comprising:

• ascertaining at least one of a light intensity and an incident position of an incident light beam on a detection surface positioned in an interior of the micromechanical component and situated with respect to the light window and the mirror element in the first position, wherein the light window, the mirror element in the first position and the detection surface are situated with respect to one another in such a way that a light beam is deflected onto the light window by the mirror element, and a portion of the light beam deflected onto the light window is reflected by the light window and at least partially strikes the detection surface;
• defining information about at least one of an instantaneous position of the mirror element with respect to the light window and an instantaneous intensity of the deflected light beam, taking into account the at least one of the ascertained light intensity and the ascertained incident position of the incident light beam;
• and
• wherein a curve over time of the ascertained light intensity on the detection surface is analyzed to detect a standstill of the mirror element, and if a standstill of the mirror element for a predefined period of time is recognized, a shutdown signal is output to a light source emitting the deflected light beam.
