Abstract:
1. Micro-mirror made up of a moving part, with a reflective zone, a fixed part, a means of connection of the moving part to the fixed part, forming an axis of rotation contained in the moving part substantially parallel to a principal plane of the moving part and means of electrical control of the rotation of the moving part about the axis, characterized by the fact that the means of electrical control include two or more actuators, each formed of a fixed electrode which forms part of the fixed part and a moving electrode possessing a free end and an end which is connected to a drive arm which is substantially parallel to the axis and emerging from the moving part, with the moving electrode being designed to adhere to the fixed electrode from its free end when an actuation voltage is applied between the two electrodes of one of the actuators, the adhesion occurs over a surface which varies as a function of the voltage applied between the electrodes of the actuator, with the actuators being arranged on either side of the axis.
