Abstract:
A multiple depth display provided for displaying images at different depths comprises a single display device (61), for displaying all of the images. An optical system (62, 63, 64) is disposed in front of the display device (61). The optical system comprises first and second spaced-apart partial reflectors (62, 63) and polarization optics (64) for providing first and second light paths for first and second images or sequences of images displayed by the device (61). The first light path (65) comprises partial transmission through the first reflector (62), partial reflection from the second reflector (63), partial reflection from the first reflector (62), and partial transmission through the second reflector (65) towards a viewing region.
