<p>An optical system is provided, for example for use with a display device (1) to convert a flat image from the display device (1) to a non-flat image. The optical system comprises first and second spaced-apart partial reflectors (3, 5), at least one of which is non-flat. The reflectors (3, 5), together with polarisation optics (2, 4), provide a light path (6) such that light from the display (1) is at least partially transmitted by the first reflector (3), partially reflected by the second reflector (5), partially reflected by the first reflector (3) and partially transmitted by the second reflector (5) so that a viewer (8) perceives a non-flat, for example curved, image. Light which does not follow the light path (6) is prevented from leaving the optical system.</p> |
