ABSTRACT:
An arrangement preventing the creation of secondary images in the case of the so called "tandem scanning" of objects by means of a scanning disk with spirally arranged openings similar to a Nipkow disk and a mirror provided on one of its surfaces with a semitransparent mirror layer in which said mirror has a thickness sufficient to space apart the light rays reflected from the mirrored and unmirrored surfaces so that only the light ray reflected from the mirrored surface will pass through the scanning disk.
