A holographic projector configured to provide a holographic picture at an output plane. The holographic projector comprises a spatial light modulator configured to display a hologram such that any light incident on the displayed hologram is spatially modulated according to the displayed hologram. The holographic projector further comprises an optical relay arranged to receive the spatially modulated light, the optical relay comprising a pair of lenses arranged in cooperation to form the holographic picture at the output plane. The holographic projector further comprises a spatial light filter comprising a portion arranged to receive the spatially modulated light. The portion blocks at least a part of the spatially modulated light and the amount of light blocked by the portion decreases as a continuous function of distance relative to a centre of the portion.
