Figure 2

Volumetric stereo 3D display. The overall design is a stereoscope with independent light paths for the two eyes. The key elements are high-speed switchable lenses in front of each eye. The lenses change focal power to one of four possible values. By synchronizing the lenses with high-frame-rate CRTs, the apparatus updates each focal plane at 45Hz. The retinal images from one focal plane become sharp when the viewer accommodates to that plane; the images from the other planes become blurred. The viewer’s optics creates this pattern of sharp and blurred images.
