Abstract:
1. A micromechanical device, comprising: a suspension; a micromechanical functional structure suspended by the suspension in the micromechanical device; an electromagnetic radiation heating element arranged such that a radiation field of the electromagnetic radiation heating element irradiates a surface of the micromechanical functional structure partially or entirely to cause a spatially and temporally defined temperature or a spatially and temporally defined temperature profile on the micromechanical functional structure; and a controller operatively connected to the electromagnetic radiation heating element and configured to adjust the spatially and temporally defined temperature or the spatially and temporally defined temperature profile; wherein the micromechanical functional structure is a spring-suspended scanner mirror which is configured to be periodically excited by an oscillating system to maintain an oscillation; and the spring-suspended scanner mirror has a resonance frequency that is controllable based on predetermined algorithm by the electromagnetic radiation heating element.
