Outline of Final Research Achievements

The Maxwellian-view is a powerful technique to provide images to persons with low-vision, because images are displayed using light converging at a crystalline lens of an eye so that retinal images are formed not depending on light refraction function of the crystalline lens. In the present study, the Maxwellian-view display was realized using the computer-generated holograms. By use of the wavefront modulation by holograms, the light converging point could be moved electrically according to the movement of eyes without using the mechanical parts. The astigmatism, which is caused by complicated distortion of the crystalline lens, could be corrected using the wavefront modulation. Especially, the irregular astigmatism could be corrected, which cannot be corrected using glasses and contact lenses. Moreover, the compact system configuration was proposed and the display system was demonstrated, which shows the possibility of the HMD implementation for the proposed technique.
