Abstract: An apparatus includes a scan module having one or more laser sources that generate one or more initial laser beams and two or more beam deflectors that deflect the initial laser beam(s).

Abstract: A MEMS device includes a movable mirror and a solid material below the mirror that removes more heat from the mirror and creates more viscous drag than if the solid material were absent while allowing free movement of the mirror. A MEMS system includes a movable mirror, transparent window, electronic package, and a fluid-tight cavity between the window and the electronic package filled with a fluid exhibiting higher thermal conductivity than air. Another system has a reflective movable mirror, transparent window, and a lid that holds the window close to the mirror without obstructing its free movement. There is greater vertical clearance between the MEMS system and lid than between the mirror and MEMS system. Another MEMS device has a movable mirror and a surrounding substrate coplanar to the mirror. A gap between the mirror and substrate is filled with fluid. Finger structures extend from the mirror into the gap.
