Computer-generated holographic images can be better seen from the side thanks to a thin metal film with millions of tiny pinholes. This \u2018photon sieve\u2019 could one day enable dynamic 3D images to be viewed on mobile devices.<\/p>\n\n\n\n

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in collaboration with SAIT Samsung Electronics placed an array of sub-micron apertures over a commercial LCD panel illuminated from behind with a laser. Light is diffracted widely as it exits the pinholes, allowing holograms to be clearly seen within a viewing angle of 30 degrees.<\/p>\n\n\n\n

Users looking at the same scene with the photon sieve removed would experience holograms with a viewing angle of just a few degrees.<\/p>\n\n\n\n

\u201cThe present demonstration is the first flat-panel holographic display capable of displaying a large-sized image with a wide viewing angle,\u201d says YongKeun Park, who has expertise in holographic microscopy and leads the Biomedical Optics Laboratory at KAIST.<\/p>\n\n\n\n

Visually captivating, holograms have immediate appeal as an entertainment medium, but their potential does not stop there.<\/p>\n\n\n\n

\u201c3D images contain a wealth of informa- tion, making holograms useful for observing changes in systems,\u201d explains Park. \u201cDisplays made using holographic recording techniques could be used for remote surgery, head-up displays for cars, augmented and virtual reality, and more.\u201d<\/p>\n\n\n\n

Holographic displays could provide a comfortable, headset-free solution for users in home and work environments. Park anticipates viewers gathering round a flat-panel holographic display, much like people watch a TV or computer screen today.<\/p>\n\n\n\n

The rapid advancement of LCDs replacing clunky tube-based TV and computer monitors motivated Park to develop a practical, attractive design for a flat-panel holographic display.<\/p>\n\n\n\n

\u201cMaking a thin device has become one of the most essential criteria for the display industry,\u201d he notes.<\/p>\n
