ABSTRACT:
In a digital light deflector which includes electrooptical polarization switches and birefringent prisms the influence of undesirably deflected radiation can be suppressed by providing, behind the final deflection stage, a lens for spatially separating the undesirably deflected radiation from the signal radiation and a radiation chopper which comprises a plurality of elements and is controlled in synchronism with the polarization switches.
