Abstract: A method and apparatus for reducing the effects of FOCUS fixation includes a multiple perspective autostereoscopic display, a controller for receiving image inputs from a source and connected to the autostereoscopic display, and together with the multiple perspective autostereoscopic display, forming a plurality of viewing zones associated with different perspectives, each of the viewing zones being smaller than the pupil of a user, and at least two of the viewing zones being coincident with a pupil of an eye of an observer without the pupil moving.

Abstract: A three-dimensional volumetric display includes an image generator for generating a three-dimensional image of a first size, a projection lens, and a double fly's eye lense in which the lenslets of a rear sheet have a shorter focal length than the lenses of a front sheet, the front sheet being the sheet closest to the projection lens.
