ABSTRACT:
The optics of the present invention are used for the cartesian scanning and reproduction of large image fields.
The optics have at least two roof prisms oscillating to and fro perpendicularly to the direction of their roof edges, for the purpose of writing the length of the image line and a conventional optical means is provided behind the roof prism, as seen in the direction of the incident light, for writing the small image angle ( =image height).
