摘要

Systems, methods and devices relating to a miniature actuable platform assembly including a miniature mirror. The assembly comprises a gimbal having first, second and third toroidal gimbal plates, the first gimbal plate being a radially innermost plate, the third gimbal plate being a radially outer most gimbal plate, and the second gimbal plate being located radially intermediate to the first and third plates, a first pair of rotational flexures extending between the first and second gimbal plates along a first axis, a second pair of rotational flexures extending between the second and third gimbal plates along a second axis, a support assembly for mechanically coupling with the first gimbal plate for supporting the gimbal, a magnet mounted on the gimbal, and a platform mounted on the magnet.
