Estimating the term…
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.
An optical system for providing a first light path which is longer than a physical length of the system,
A display comprising a display device for modulating a first light with a first image or sequence of images and an optical system arranged to increase the perceived depth of the location of the first image or sequence, the optical system comprising first and second spaced-apart partial reflectors and providing a first light path for the first light from the device to a viewing region, the first light path comprising at least partial transmission through the first reflector towards the second reflector, at least partial reflection from the second reflector towards the first reflector, at least partial reflection from the first reflector towards the second reflector, and at least partial transmission through the second reflector towards the viewing region.
