This paper reports a secondary scan mirror for step-stare lidar applications that is single axis and operates in a non resonant mode. The mirror has a resonant frequency of 61 kHz and a diameter of 2 mm with angular scan range equivalent to 10 resolvable spots at 780 nm. Hand calculations and finite element simulations showed good correlation with experimental results. The mirror, which is 300 μm thick, achieves torsional motion through electrostatic force electrodes placed 3 µm beneath it. Simulations and measurements suggest that static and dynamic mirror deformation remains below the diffraction limit.
