Abstract
A scanner system and method are described, wherein two lenses are mounted on a slider positioned in the optical light path between two moving mirrors and the optical sensor. Each mirror is mounted on a moving carriage. The slider is bistable in two alignment positions, one for each lens. The slider is moved by the motion of one of the carriages. As the carriage moves toward the lens slider, a linkage causes the slider to move from the position it is currently in to the other position. This system allows the slider to be shuttled from one position to the other, thereby changing resolutions, using energy provided by the same motor that moves the mirrors.
