ABSTRACT:
A light deflecting device for use in a light scanner, comprises a deflector (4) and a dove prism (13) mounted together on a rotatable support (16). The support (16) rotates about a nominal axis (2) coaxial with an incident light beam direction (11). A beam is incident on the deflector (4) so as to be deflected through a fixed angle (.THETA.) relative to the nominal axis (2) independently of any angular movement of the support (16) about the nominal axis.
