Abstract (en)

[origin: WO2009007139A1] The present invention relates to a micromechanical apparatus having a moving element which comprises a controllable heating apparatus for introduction of a defined amount of heat into the moving element, wherein the apparatus furthermore has a control unit (5) which is designed to control the heating apparatus as a function of an instantaneous temperature and/or of an instantaneous amount of heat that is introduced. By way of example, the apparatus can be designed to project electromagnetic radiation when the moving element is in the form of a beam deflection unit (2) for deflection of radiation, which originates from a radiation source (1), onto a projection surface (3). Finally, the invention also relates to a corresponding method for projection of electromagnetic radiation.
