Abstract

A display system (300) comprising an optical system and a processing system. The optical system comprising a spatial light modulator (380), a light source, a Fourier transform lens, a viewing system (320, 330) and a processing system. The spatial light modulator is arranged to display holographic data in the Fourier domain, illuminated by the light source. The Fourier transform lens is arranged to produce a 2D holographic reconstruction in the spatial domain (310) corresponding to the holographic data. The viewing system is arranged to produce a virtual image (350) of the 2D holographic reconstruction. The processing system is arranged to combine the Fourier domain data representative of a 2D image with Fourier domain data representative of a phase only lens to produce first holographic data, and provide the first holographic data to the optical system to produce a virtual image.

Dependent claims

A method for displaying a virtual image to a viewer, the method comprising:

providing Fourier-domain data representative of a first two-dimensional (2D) image;
providing first Fourier-domain lensing data representative of a first optical power;
writing the Fourier-domain data representative of the first two-dimensional image and the first Fourier-domain lensing data to a phase-modulating spatial light modulator;
providing light from a light source;
producing, as a real image in space spatially remote from the viewer, a first 2D holographic reconstruction image, by modulating the light with the spatial light modulator and performing a Fourier transform on the light;
and
displaying a first virtual image of the first 2D holographic reconstruction image using an optical viewing system.
