The principle of the proposed II display which can enlarge the
depth of II is based on double-device systems. It is improved that
integral imaging can be enhanced in image depth by adopting
double-device systems [17]. As shown in Fig. 1, the proposed II display consists of a display panel, a plano-convex micro-lens array,
a flat-panel array, and an optical barrier array. The display panel is
used to display the elemental images. The plano-convex micro-lens
array is used to reconstruct the 3D images. The optical barrier array
is used to eliminate the crosstalk. The flat-panel array has an interlaced arrangement and is attached to the plano-convex micro-lens
array, and it makes the plano-convex micro-lens array becomes
a double-device. Because of using the flat-panel array, the front
principle planes of the plano-convex micro-lenses are shifted over
a distance, thus, the object distances are changed, and so do the
image distances according to the lens law. Therefore, the proposed
II display can enhance the depth of II by creating two CDPs.
Fig. 2 shows the schematic of the proposed II display. The planoconvex lens is denoted as lens 1, the plano-convex lens with flatpanel is denoted as lens 2. Conveniently, we assume that lens 1 and
lens 2 display real images simultaneously. The front principle plane
H2 of lens 2 moves a distance of l relative to the front principle
plane H1 of lens 1. The distance l is given by
