Abstract
A mechanical scanning dual-image display device utilizes two separate scanning mirror mechanisms with a common control that forces the scanning mirrors to move in opposition, and substantially cancel reaction forces. This cancellation is accomplished by providing each of the mirrors with an individual drive mechanism, commonly controlling the two drive mechanisms and arranging the geometry of each display so that the reaction forces acting on the overall display as a result of the mirror motion cancel. In a second embodiment, vibrations are reduced by driving both mirror assemblies from a common source. More specifically, both mirrors are oscillated by an eccentric and linkage mechanism driven by a common motor.
