The picture scanning attachment consists of a high resolution optical reflective sensor and associated amplification stages, in the form of a small probe which replaces the pen and pen holder in an incremental plotter and thus allows shaded pictures to be scanned for subsequent processing by digital computer.

Received September 1980.
