Paper Abstract

The purpose of an analytical orthoprojector is the computer-controlled rectification of aerial photographs into a parallel perspective orthophoto. For the optical transformation the aerial photographs are scanned with a small slit. Each picture element must be exposed onto a specific position in the orthophoto at a specific magnification and orientation (rotation). The density of the orthophoto must be uniform without visible strips. Hence the basic requirements for the optical system are: large range zoom, uniform slit illumination independent of zoom position, image rotation, high boresight stability for projecting beam. The optical design of the Zeiss orthoprojector ORTHOCOMP Z 2 is discussed.
