Journal ArticleDOI
Projection-type see-through holographic three-dimensional display.
Koki Wakunami,Po Yuan Hsieh,Ryutaro Oi,Takanori Senoh,Hisayuki Sasaki,Yasuyuki Ichihashi,Makoto Okui,Yi-Pai Huang,Kenji Yamamoto +8 more
TL;DR: A projection-type holographic three-dimensional display is shown, in which a digitally designed holographic optical element and a digital holographic projection technique are combined to increase both factors at the same time.
Journal ArticleDOI
Fast calculation of computer-generated-hologram on AMD HD5000 series GPU and OpenCL
TL;DR: Using a RV870 GPU and OpenCL, a CGH from a 3D object consisting of 1,024 points in 30 milli-seconds is calculated, a speed approximately two times faster than that of a GPU made by NVIDIA.
Journal ArticleDOI
Large size three-dimensional video by electronic holography using multiple spatial light modulators
TL;DR: A newly devised space-saving image-readout optical system for multiple reflection-type SLMs to increase the size of three-dimensional (3D) images that are displayed using electronic holography.
Journal ArticleDOI
Image Size Scalable Full-parallax Coloured Three-dimensional Video by Electronic Holography
TL;DR: The experimental device constructed was able to perform video playback in colour of full parallax holographic three-dimensional images with an image size of 63 mm and a viewing-zone angle of 5.6 degrees without losing any part of the 3D image.
Journal ArticleDOI
Band-limited double-step Fresnel diffraction and its application to computer-generated holograms.
Naohisa Okada,Tomoyoshi Shimobaba,Yasuyuki Ichihashi,Ryutaro Oi,Kenji Yamamoto,Minoru Oikawa,Takashi Kakue,Nobuyuki Masuda,Tomoyoshi Ito +8 more
TL;DR: Band-limited double-step Fresnel diffraction will be useful for large computer-generated holograms (CGHs) and gigapixel digital holography, mitigating the aliasing noise of the DSF.
