    • The invention relates to active microoptic reflecting components for adapting or changing the focal length or focal position in optical systems. It is the object of the invention to make available a miniaturised reflecting microoptic component for focusing or defocusing incident electromagnetic radiation, with which a variation in the focal distance can be achieved simply and at low cost. On the component according to the invention there is an elastically deformably membrane which is formed at least with one reflecting layer comprising a first material or material mixture and at least with one further layer or substrate which is formed from a second material or material mixture. First and second materials or material mixtures have thermal coefficients of expansion which deviate from each other. In addition a heating or temperature control mechanism is present.

    • The invention relates to deflectable micromechanical systems as well as their use in which the deflection of at least one deflectable element can be determined. In accordance with the invention, a deflectable element is held with at least one spring element and at least one unit detecting the deflection is present. It is formed as a piezoresistive sensor with contacts arranged at least at a spacing from one another and in a region deforming on deflection. The contacts are connected to an electrical voltage source. An inhomogeneous electrical field is formed perpendicular to the contact surfaces in the depth direction so that the electrical resistance between contacts varying in dependence on the deflection can be detected as a measure for the position. The deforming region is formed from electrically conductive or semiconductive material.
    • 本发明涉及可偏转的微机械系统以及其可以确定至少一个可偏转元件的偏转的用途。 根据本发明,可挠曲元件被保持有至少一个弹簧元件,并且存在检测偏转的至少一个单元。 它形成为压阻传感器,其触点至少彼此间隔开并且在偏转变形的区域中布置。 触点连接到电压源。 在深度方向上垂直于接触表面形成不均匀的电场,使得可以检测根据偏转而变化的触点之间的电阻作为位置的量度。 变形区域由导电或半导体材料形成。
