Abstract
Very high geometric and radiometric resolution requirements must be met by the digitization of photogrammetric aerial images or entire aerial films. Flat bed scanners scanning with CCD arrays are used in this field. The optical design will be discussed in detail. A scanner designed by Carl Zeiss will be used to illustrate alternative illumination and lens systems which project the aerial image onto a CCD array. An Offner catoptric system is shown to be superior to a conventional refractive lens.
