There is discussed volumetric display apparatus including an imaging system having an object plane and an image plane, source image generation apparatus for forming a source image in the object plane in accordance with received image data, and control apparatus for supplying image data to the source image generation apparatus, the image data corresponding to a series of two-dimensional images. The source image generation apparatus includes a light source and the imaging system includes a diffractive optical element. The control apparatus is arranged to generate at least one control signal to vary at least one of a wavelength of light emitted by the light source and a focal length associated with the diffractive optical element to vary the location of said image plane within a volume of real space in synchronism with the formation of the series of two- dimensional images in the object plane so as to construct a volumetric three- dimensional image in accordance with the received image data. |
