专家简介：
Osamu Matoba received his M.S in 1993 and Ph.D. in 1996 from Applied Physics at Osaka University. In 1996, he became an assistant professor in the University of Tokyo. In 2002, he moved to Kobe University as Associate Professor. In 2009, he became a full Professor in the Department of System Science in Graduate School of Engineering. Now, he is a professor and is the director of Center of Optical Scattering Image Science, Kobe University. His research interests include holography, holographic microscope for neuroscience, imaging through scattering medium, and computational imaging. He is author or co-author of more than 150 peer-reviewed journal papers in the fields of applied optics and optical sensing. He received the 2008 IEEE Donald G. Fink prized paper award. He is Fellows of SPIE and Optica.
讲座简介：
I will review my research history. First, in 1991, I started computer simulations of convolutional neural networks similar to CNN for image processing in 1991. Since computer power was quite low at that time, I decided to change my research to the development of optical neural network using photorefractive waveguides. After I received my Ph.D from Osaka University in 1996. I became an assistant professor in Prof. Kuroda’s lab in the University of Tokyo in 1996. I met Prof. Xiaodi Tan at Prof. Kuroda’s lab. In 1998, I had the opportunity to spend a year in Prof. Bahram Javidi’s lab at the University of Connecticut. In his lab, I developed secure holographic memory systems using optical encryption techniques. This is the first topic in holography. During his lab, I also learned the digital holography for numerical reconstruction and integral imaging for 3D display. I moved to Kobe University in 2002. My research interests are reflection-type holographic memory and digital holography. One of my achievements in reflection-type holographic memory is to estimate the maximum storage capacity considering the amount of cross-talk noise. Now, I am working on the incoherent digital holography and holographic microscopy for biological applications and neuroscience. The transport of intensity equation that is one of the quantitative phase measurement, is applied to three-dimensional fluorescence imaging. I am also working on the imaging technique passing through scattering medium. Holographic microscopy and imaging through scattering media are lead to three big research projects. Owing to fruitful research activity of these researches, it makes up the creation of Research Center in Kobe University.
