The multi-plane, volumetric display. A) Schematic of the display. The observer's eyes are shown on the left. The three image planes are shown at 31.1, 39.4, and 53.6 cm (3.21, 2.54, and 1.87D, respectively). The images from the planes are superimposed at the eyes with mirrors and beam splitters (not shown). The viewing frusta for the left and right eyes are represented by the green and red shading, respectively. The vertical and horizontal fields of view for each eye are 8.8 and 18.7°, respectively. The brown shading represents the region of binocular overlap. B) Photograph of the display with an observer in place. Periscope optics are used to align the two eyes with the viewing frusta. Head position is fixed with a bite bar. Accurate alignment of the eyes with viewing frusta is crucial to achieve the correct superposition of the images at the retinas. This is achieved by using an adjustable bite-bar mount and hardware and software alignment techniques (Akeley et al., 2004; Hillis & Banks, 2001).
