HOLOGRAPHIC PROJECTION

A holographic system comprises an image processing engine, a hologram engine and a display image. The image processing engine is arranged to determine first and second secondary images by sampling the pixel values of a primary image at a regular array of sampling positions. The hologram engine is arranged to determine a hologram of each secondary image. The display engine is arranged to display each hologram in rapid succession on a display device, first and second times, so as to reconstruct each secondary image from the respective hologram such that respective first and second arrays of image pixels corresponding to the primary image are perceivable. Image pixels of the reconstruction of the second secondary image are interposed between image pixels of the reconstruction of the first secondary image in the first direction. An aperture of the display is orientated such that it is longer in the second direction than the first direction, wherein the image pixels are more elongate and closely-packed in the first direction than the second direction.
