Abstract
A scanning device includes a base containing one or more rotational bearings disposed along a gimbal axis. A gimbal includes a shaft that fits into the rotational bearings so that the gimbal rotates about the gimbal axis relative to the base. A mirror assembly includes a semiconductor substrate, which has been etched and coated to define a support, which is fixed to the gimbal, at least one mirror, contained within the support, and a connecting member connecting the at least one mirror to the support and defining at least one mirror axis, about which the at least one mirror rotates relative to the support.
