Double-sided scanning micromirror array for autostereoscopic display

This paper reports a double-sided scanning micromirror array for an autostereoscopic display. Double-sided micromirrors actuated by both external magnetic force and Lorentz force were designed and fabricated using MEMS technology, and some characteristics of a micromirror were measured. A micromirror array, two pinhole arrays, microlenses, and an LED matrix were assembled into a prototype autostereoscopic display, and the relation between the view angle and the light intensity was measured under some conditions. The light intensity distribution of this prototype demonstrated the feasibility of using double-sided micromirror arrays to make autostereoscopic displays.
