Abstract:
1. A method for securing and controlling a micro-mirror, the method comprising: directly connecting three or more supporting springs to a micro-mirror at selected spaced apart locations to provide a restoring force for each of at least two rotational degrees of freedom of movement of the micro-mirror, where the spring connection locations form a conceptual polygon and the supporting springs maintain a length-to-thickness ratio selected so that the supporting springs operate primarily in a tensile mode; electro-statically actuating the micro-mirror by three or more spaced apart driving electrodes located adjacent to the micro-mirror, with each driving electrode being independently controlled; and providing the micro-mirror with a frame including dielectric material positioned close to at least one edge of the micro-mirror and positioned between a first material layer that contains the micro-mirror and a second material layer that contains the supporting springs.
