Abstract
A compact optical scanner includes a base unit and a scan unit. The base unit includes an optical source such as a laser and an optical path directing a beam emitted by the laser to a scan mirror which is located in and supported by the scan unit. As the scan mirror rotates, the optical beam is reflected back to the base unit from which it is emitted as a beam scanning to and fro in a scan plane. The scan unit is supported by reference to the base unit such that the oscillation axis of the scan mirror is substantially and preferably parallel to the scan plane.
