Claim:
1. A display system for displaying a virtual image of a first two-dimensional (2D) image to a viewer, the display system comprising: a processing system configured to combine data representative of a Fourier transform of the first 2D image with Fourier-domain data representative of a first phase only lens to produce first holographic data; a phase modulating spatial light modulator arranged to display the first holographic data; a light source arranged to illuminate the spatial light modulator to form spatially modulated light in accordance with the first holographic data; a Fourier transform lens arranged to Fourier transform the spatially modulated light and produce a first 2D holographic reconstruction image of the first 2D image, the first 2D holographic reconstruction image being a real image in space spatially remote from the viewer; and a viewing system arranged to display a first virtual image of the real 2D holographic reconstruction image to the viewer.
