Micromechanical Scanners


image4research

Microfabricated mechanical scanners are strong tools for optical microscopy, image sensors, and displays. We have utilized silicon microscanners for hand-held confocal miscopy, optical coherence tomography (OCT), compound eye-shaped robot vision system, and ultra-resolution full color displays. The image is a 2D nanopositioning scanncer made of 3D printed titanium flexure.
