1. A display device comprising:
a directional illuminator for providing a light beam;
a display panel downstream of the directional illuminator, for receiving and spatially modulating the light beam to provide a spatially modulated light beam carrying an image in linear domain;
a beam redirecting module downstream of the display panel, for variably redirecting the spatially modulated light beam; and
an ocular lens downstream of the beam redirecting module, for forming an image in angular domain at an eyebox of the display device from the image in linear domain carried by the spatially modulated light beam and redirected by the beam redirecting module.

11. A display device comprising:
a light source for providing a light beam;
a pupil-replicating lightguide downstream of the light source, for expanding the light beam to provide an expanded light beam;
a display panel downstream of the pupil-replicating lightguide, for receiving and spatially modulating the expanded light beam to provide a spatially modulated light beam carrying an image in linear domain;
a beam redirecting module downstream of the display panel, for variably redirecting the spatially modulated light beam; and
an ocular lens downstream of the beam redirecting module, for forming an image in angular domain at an eyebox of the display device from the image in linear domain carried by the spatially modulated light beam.

16. A method for displaying an image to a user, the method comprising:
providing a light beam;
receiving and spatially modulating the light beam to provide a spatially modulated light beam carrying an image in linear domain;
using a beam redirecting module to variably redirect the spatially modulated light beam towards an eye of the user; and
forming, by an ocular lens, an image in angular domain from the image in linear domain carried by the spatially modulated light beam and redirected by the beam redirecting module.
