Chapter 6:
Multiplexing Techniques in Autostereoscopic Displays
The size of each pixel and the resolution of a 2D display are essential factors when deciding the quality of reconstructed 3D images. The employment of projection-optics systems is beneficial because the size of a pixel can be freely adjusted. The resolution can also be multiplied by tiling multiple projectors. The maximum pixel density depends on the viewing distance of the system. The recommended viewing distance for larger displays is also increased as mentioned in Chapter 1. Consequently, a pixel density of less than 100 ppi is enough to provide the maximum spatial frequency with 2 m of the viewing distance, as illustrated in Fig. 1.6.
