Prof. Yoshiharu Morimoto
Proffessor Yoshiharu Morimoto (Nickname: Harry Moiré) is currently Emeritus Professor at Wakayama University, Chairman of 4D Sensor Inc., and Representative Director of Moire Institute Inc. He is developing 3D shape and deformation measurement systems.He graduated Master course of Osaka University, Japan in 1968 and received Dr. Eng. from Osaka University in 1981. His major field of study is experimental mechanics and image processing.He joined Komatsu Ltd. in 1968. He returned Osaka University as Associate Researcher in 1974. He moved to Wakayama University in 1995.He was Professor of Dept. of Opto-Mechatronics, Faculty of Systems Engineering, Wakayama University, Japan. He was also Vice-President and Executive Director for Research & University Liaison of Wakayama University,He retired from Wakayama University in 2009 and established Moire Institute Inc. in 2009, and 4D Sensor Inc. in 2012. He is Fellow of SEM, former Executive Board Member of SEM, Fellow of JSME, Honorary member of JSEM, the former President of JSEM and former Chairman of Asian Committee for Experimental Mechanics. He received awards, from JSNDI, JSME, JSP, SEM and JSEM.His current and previous interests are following measurement methods for shape, deformation, stress and strain:
(1) Scanning moiré method using TV camera
(2) Phase analysis methods using Fourier, wavelet or Gabor transforms
(3) Strain rate distribution measurement by a high-speed video camera
(4) Real-time integrated phase-shifting method
(5) High-speed and accurate methods using multi-reference planes, a DMD, a linear image sensor, or a frequency modulated grating
(6) Real-time simultaneous measurement for two-directional stress or strain distributions
(7) Accurate 3D displacement and strain measurement by phase-shifting digital holographic interferometry.
(8) 3D shape measurement using whole space tabulation method and LED light sources.
(9) Shadow moire method using light source stepping method
