ABSTRACT:
A holographic display system comprising left and right optical systems is disclosed. The optical systems each comprise an image display operable to display an input image and first and second holographic devices. The first holographic device 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 first aspect ratio. The second holographic device 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. A method of changing the aspect ratio of an image is also disclosed.
