Abstract
A mechanical, electrical and optical scanning apparatus for producing a digital image of a two-dimensional original object in which the combined motions of multiple platforms or carriages along one dimension of the two-dimensional original object provides both low resolution scan of the original object and high resolution scan of the original object as well as intermediate resolutions. One of the platforms carries a camera with precision zoom/focus control for receiving light energy from said original object along the other of its dimensions converting it into electrical energy in a digital format. This platform provides low resolution scanning. The other platform carries the original object and provides high resolution scanning but moves only a fraction of the length of the original object. Combined motion of the two platforms provides high resolution scanning along the entire length of the two-dimensional original object.
