OSA To Host Digital Holography & 3-D Imaging Meeting in Tokyo

Scientific meeting will highlight latest research advances in 3-D TV, holographic displays and imaging

WHAT: The Optical Society’s (OSA) 2011 Digital Holography (DH) and Three Dimensional (3-D) Imaging  Meeting

WHEN: 9–11 May, 2011

WHERE: University of Tokyo, Komaba Research Campus, Tokyo, Japan

Chaired by George Barbastathis of MIT, USA and Toyohiko Yatagai of the Center for Optical Science and Education (CORE) at Utsunomiya University, Japan, and sponsored by the Optical Society, the topical meeting on Digital Holography and Three-Dimensional Imaging provides a forum for disseminating the fundamentals and applications of holographic and digital methods in optical science and technology. Topics to be addressed include optical data storage, computer-generated holograms, 3-D imaging, 3-D display, holographic imaging and microscopy, and more.

DH 2011 features the highest number of paper submissions since the meeting's inception. The program is truly international in scope with research from Asia, North and South America, Europe and Australia being presented. Notably, more than one third of the accepted papers are from Japan.

Research being presented from teams in Japan includes:

Title: Integral 3D TV Using the Pixel-Offset Method with Four 33-Megapixel Image Sensors
Author: Jun Arai,NHK, Japan Broadcasting Corporation, Japan.
Abstract: We have developed integral 3-D television image capture equipment using four 33-megapixel image sensors. By capturing elemental images that exceed the Nyquist frequency of a 33-megapixel image sensor, we could suppress aliasing and improve resolution.

Title:  fVisiOn: Glasses-free Tabletop 3-D Display--Its Design Concept and Prototype
Author: Shunsuke Yoshida, NICT, Japan.
Abstract: fVisiOn is a novel, glasses-free tabletop 3-D display designed for tabletop interaction scenarios. It floats virtual 3-D objects on a flat tabletop surface and provides a natural mixed-reality environment for multiple people around the table.

Title: Three-Dimensional Imaging by Portable Parallel Phase-Shifting Digital Holography System
Authors: Motofumi Fujii, Takashi Kakue, Peng Xia, Kenichi Ito, Tatsuki Tahara, Yuki Shimozato, Yasuhiro Awatsuji, Kenzo Nishio and Shogo Ura of Kyoto Institute of Technology, Japan;  Toshihiro Kubota of Kubota Holography Lab. Corp., Japan, and Osamu Matoba of  Kobe University, Japan.
Abstract:We constructed a portable parallel phase-shifting digital holography system. The size and weight of the system are 450mm × 250mm × 200mm and 7kg, respectively. We succeed in three-dimensional imaging of objects with the system.

Title: 25 Hz en-face Low-Coherent Quantitative Reflection Phase Imaging of Living Cells
Authors: Toyohiko Yamauchi, Hidenao Iwai, and Yutaka Yamashita of Hamamatsu Photonics, Japan.
Abstract:The surface motion of a living cell is imaged in 25 Hz frame rate. The setup is based on an interference microscope with sub-nanometer optical-path length control.

Title: Digital Holographic Profilometry Applied to an Inspection of a Pipe Inner Surface
Authors: Masayuki Yokota and Toru Adachi of Shimane University, Japan.
Abstract:Digital holography has been applied to a measurement of an inner surface profile of a pipe. The shape of two pieces of metal sheet pasted on the inner surface and a hole made in the wall can be detected and evaluated with a digital image processing.

Title: Hybrid CGH by Digitized Holography: CGH for Mixed 3-D Scene of Virtual and Real Objects
Authors: Yasuaki Arima, Kyoji Matsushima , and Sumio Nakahara of Kansai University, Japan.
Abstract:A hybrid CGH reconstructing 3-D scenes including virtual and real objects is created.
The large-scaled wave-field of a real-existent object is captured by synthetic aperture digital holography and mixed with the virtual 3-D scene.
