A holographic system comprises a spatial light modulator and a pupil expander. The spatial light modulator is arranged to display a hologram of an image and to output spatially modulated light encoded with the hologram. In embodiments, the pupil expander comprises a plurality of optical fibres, each optical fibre having an input end and an output end. The pupil expander is arranged so that spatially modulated light output by the spatial light modulator is coupled into the input end of each optical fibre and output from the output end thereof to a viewing area. Each of the plurality of optical fibres is arranged to propagate the received spatially modulated light received at its input end so as to expand an exit pupil of the system in a first dimension, typically corresponding to a dimension of the viewing area.
