ABSTRACT:
An apparatus for the photoelectric measurement of an essentially planar measurement original includes a photoelectric scanner and a positioning arrangement for the two dimensional movement of the scanner over the measurement original positioned on a supporting surface and the positioning at defined measurement locations on the measurement original. The positioning arrangement is constructed as a type of SCARA robot and includes a stationary base, a first and a second movable robot arm and a positioning control. The first robot arm is mounted on the stationary base for rotation by a motor about a first axis of rotation perpendicular to the supporting surface. The second robot arm is mounted at the free end of the first robot arm for rotation by a motor about a second axis of rotation perpendicular to the supporting surface and carries the scanner, and the positioning control is constructed for rotation of the two robot arms according to externally supplied positioning commands. The apparatus requires relatively little mounting space, is suitable for both remission and transmission measurements, and can be realized at relatively low construction cost.
