Abstract
A scan unit for an imaging device having a movable mirror and one or more light sources. A light beam generated by each light source is directed towards the movable mirror, movement of the mirror causing each light beam that is reflected by the mirror to follow a distinct scan pattern. An optical assembly is associated with each reflected light beam to form an optical path for each reflected light beam from the mirror. A housing in which the movable mirror, the one or more light sources and the optical assembly are secured has at least a portion made from electrically conductive material for shielding an interior of the housing from electromagnetic fields external to the housing. A light drive circuitry card is disposed in the interior of the housing and communicatively coupled to the one or more light sources for driving the one or more light sources.
