A volumetric imaging apparatus has a volumetric image generator with a light source, a light modulator, and a display surface. The volumetric image generator is energizable to form, on the display surface, an image over a range of focal positions at the entrance pupil of an optical system. The optical system is disposed to direct light from the image to a one-dimensional pupil expander. A combiner surface is disposed in the path of output light from the pupil expander for displaying the volumetric image.
