Scanning electron mirror microscopy [PDF]
Scanning, 1981 AbstractThe working principles, instrument designs, and applications of scanning electron mirror microscopy are reviewed. The capability of this technique for direct imaging of topographical surface structures as well as electrostatic and magnetic surface strayfields is demonstrated by a number of examples.

Analysis of Error Sources in the Lissajous Scanning Trajectory Based on Two-Dimensional MEMS Mirrors
Photonics, 2023 Deviations or distortions in the trajectoy of MEMS-based Lissajous scanning imaging platforms might be detrimental to imaging quality. These deviations often arise from differences in MEMS mirror frequency response characteristics and asymmetry in ...
