Viewing zone enlargement method for holographic displays based on the slanted pixel arrangement on a spatial light modulator

This study proposes a method for enlarging the viewing zone of holographic displays using the slanted arrangement of pixels on a spatial light modulator (SLM). The pixel arrangement equivalently reduces the horizontal pixel pitch, which enlarges the horizontal viewing zone of displays. Computer-gene...

Description
Summary:This study proposes a method for enlarging the viewing zone of holographic displays using the slanted arrangement of pixels on a spatial light modulator (SLM). The pixel arrangement equivalently reduces the horizontal pixel pitch, which enlarges the horizontal viewing zone of displays. Computer-generated holograms (CGHs) were calculated using an asymmetric band-limit filter corresponding to the asymmetric bandwidth of the SLM with slanted pixels. The proposed methods were evaluated through an optical reconstruction experiment using static holograms with a pixel size of 1×1µ , fabricated via electron-beam lithography. The enlarged horizontal viewing zone angle was found to be 41.6°.
