Micromirror with comb drives for actuating mirror and mount
A recently granted patent (Publication Number: US11927741B2) discloses a unique micromirror design that includes a mirror pivotally attached to a mount by a first pivoting structure, allowing pivotal movement about a first axis. The micromirror also features a first comb drive for actuating the mirror, a weight connected to the mirror on the opposite side of a fulcrum, and a first support structure allowing pivotal movement of the mount about a second axis. Additionally, a second comb drive is included for actuating the mount about the second axis, with the weight positioned strategically between the second comb drive and the fulcrum. This innovative design enhances the functionality and precision of the micromirror.
Furthermore, the patent extends to a micromirror array comprising multiple micromirrors, each incorporating the unique design elements of the individual micromirror. This array includes a combination of mirror, mount, comb drives, weight, and support structures, all working together to enable precise actuation and movement of the micromirrors. The inclusion of a third comb drive in each micromirror further enhances the actuation of the mirror about the first axis, providing a comprehensive and efficient micromirror array solution. Overall, this patented technology represents a significant advancement in micromirror design and functionality, with potential applications in various industries requiring precise optical manipulation.
