Abstract

A scanning device includes a base and a gimbal, mounted within the base so as to rotate relative to the base about a first axis. A first mirror, which has a first area, is mounted within the gimbal so as to rotate about a second axis, which is perpendicular to the first axis. A second mirror, which has a second area that is at least twice the first area, is also mounted within the gimbal so as to rotate about a third axis, which is parallel to the second axis, in synchronization with the first mirror.
