WASHINGTON --Research into digital holography (DH), the process of electronically recording and numerically reconstructing an optical field, has made tremendous strides in recent years. To highlight breakthroughs in this area, the editors of the Optical Society's (OSA (http://www.osa.org)) journal Applied Optics (http://www.opticsinfobase.org/ao/home.cfm) have teamed with the editors of the journal Chinese Optics Letters (http://www.opticsinfobase.org/col/home.cfm) to publish a special Focus Issue on Digital Holography and 3-D Imaging (http://www.opticsinfobase.org/ao/issue.cfm?volume=50&issue=34). The issue was organized and edited by Guest Editors Ting-Chung Poon from the Bradley Department of Electrical and Computer engineering at Virginia Tech in Blacksburg, Va.; Changhe Zhou from the Shanghai Institute of Optics and Fine Mechanics at the Chinese Academy of Sciences in Shanghai, China; Toyohiko Yatagai from the Center for Optical Research and Education at Utsunomiya University in Tochigi, Japan; Byoungho Lee from the School of Electrical Engineering at Seoul National University in Seoul, Korea; and Hongchen Zhai from the Institute of Optics at Nankai University in Tianjin, China.
The focus issue features a selection of topics that were presented at OSA's DH and 3-D Imaging topical meeting (http://www.osa.org/Meetings/Archives/2011/DH-2011-Archive.pdf) in Tokyo in May. Topical meeting presentations covered the fundamentals and applications of holographic and digital methods in optical science and technology including 3-D display, optical remote sensing, optical image processing, and holographic microscopy.
In addition to increasingly popular 3-D movies and displays, DH and 3-D imaging are widely known for their biomedical imaging applications, as digital holographic microscopy provides a non-invasive method for visualizing and quantifying biological specimens. DH is also used in structural analysis, fluid flow measurement, and 3-D image processing.
