ABSTRACT:
The disclosure describes a scanning optical system in which the scanning beam from a light source is deflected by a beam deflecting device to scan the scanning plane through a scanning beam focusing lens. The scanning optical system comprises a member disposed between the beam deflecting device and the focusing lens for reflecting a part of the scanning beam a plurality of times within the member so as to take up part of the beam as an information beam.
