Micromirror with comb drives for actuating mirror and mount
A recently granted patent (Publication Number: US11927741B2) discloses a 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 and a weight connected to the mirror on the opposite side of a fulcrum. Additionally, a first support structure is pivotally attached to the mount by a second pivoting structure, enabling movement about a second axis. A second comb drive is included for actuating the mount, with the weight positioned strategically between the second comb drive and the fulcrum.
Furthermore, the patent extends to a micromirror array comprising multiple micromirrors, each with similar design features as the individual micromirror described earlier. Each micromirror in the array includes a mirror pivotally attached to a mount, a first comb drive for actuation, and a weight connected to the mirror. The array also incorporates a first support structure for pivotal movement about a second axis and a second comb drive for actuating the mount. The strategic positioning of the weight and comb drives enhances the functionality of the micromirror array, allowing for precise control and movement. Additionally, each micromirror in the array may include a third comb drive for further actuation about the first axis, contributing to the overall performance and versatility of the micromirror array design.
