Toyohiko Yatagai received BE and PhD in applied physics from the University of Tokyo, in 1969 and 1980, respectively. From 1970 to 1983 he was with Institute of Physical and Chemical Research. He joined the faculty of Institute of Applied Physics, University of Tsukuba in 1983, where he worked on optical instrumentation and optical information processing. In 2007 he moved to Utsunomiya University to launch Center for Optical Research and Education. He is a fellow of SPIE, OSA and JSAP. He was the president of Japan Society of Optics in 2009-2010 and the president of SPIE in 2015. His current research interests include optical measurement, 3-D imaging and display and holographic optical memory.
