Title:
HOLOGRAPHIC DISPLAY WITH SWITCHABLE ASPECT RATIO
Document Type and Number:
WIPO Patent Application WO2000026706
Kind Code:
A9
Abstract:
A holographic display system comprising left and right optical systems (26, 28). The optical systems each comprise an image display operable to display an input image and first and second holographic devices. The first holographic device (34) is operable to project the input image to overlap with the input image projected from the other of the left or right optical systems to form a resultant image with a first aspect ratio. The second holographic device (36) is operable to project the input image to overlap with the input image projected from the other of the left and right optical systems to form a resultant image with a second aspect ratio, different from the first aspect ratio.
