An optically-based and image processing-based scanner including a lens array, an imager, and an array of baffles to define paths of light between the lenses and the imager. Each of the lenses produces an inverted image of a portion of the object to be imaged. Components in the imager transpose and filter the individual images, or vice-versa, and assemble a composite image of the entire object. An array of plano-convex lenses is preferred.
