Fig. 2From: Multifocal displays: review and prospectClassification of methods to enable multifocal displays. The multifocal enabling methods can be categorized into power-based and distance-based ones, depending on the focal plane generating mechanism. The other classification standard is how the 2D information is multiplexed into 3D scenes. The current multiplexing channels include space, time, polarization, wavelength and their hybridsBack to article page
