Abstract
A system (100), apparatus (110), and method (900) for displaying an image (880). The light (800) in the image (880) is modified by a tuning assembly (700) to possess more than one focal point (870). Thus a single image (880) can include multiple depth regions (860). Each depth region (860) can be comprised of light (800) possessing a distinct focal point (870). The tuning assembly (700) can be implemented in the form a tunable lens (710), a tunable lens array (720), a movable lens (730), or a deformable mirror (740).
