Abstract

This paper describes in detail our concept of quasi-static micro scanning mirrors enabling large static deflections and linearized scanning using vertical out-of-plane comb drives. The vertical comb configuration is realized from a planar scanner substrate by wafer bonding. The device concept is highly flexible by design; different kinds of vertical combs (e.g. staggered and angular) can be realized without changing the technological process flow but by design modifications, only. First demonstrator devices are presented: a) quasi-static 1D-scanners with 4 mm mirror diameter and ±7.5° mechanical tilt angle for beam steering and b) a quasi-static / resonant 2D-scanner enabling 2D raster scanning with SVGA resolution.
