Method and arrangement for imaging a primarily two-dimensional target

摘要

For imaging a two-dimensional target and ensuring scanning, photography and digitalization of the surface of a museum piece book opened at an angle slightly exceeding 45°, a method includes matching at least one optical unit adapted for influencing the direction of light rays falling onto it with the target, illuminating the target while directing an optical recording element to the optical unit and turning away the optical recording element, displacing in a receding manner from the plane of the target at a predetermined angle in a curved course compared to the optical axis originating from the target centre while tilting a mirror to half the extent of displacement, and mapping the pixels of the target reaching the optical recording element by projecting the rays originating from the pixels at right angles to the target through the optical unit to sensor elements.
