Abstract

In this paper, a high-impact resistive lateral-shift-free (LSF) electrothermal micromirror is proposed. The new bimorphs of the micromirror are composed of photosensitive polyimide (PSPI) and Al. Compared with the traditional micromirror, the impact resistance has been improved about 30 times.
