Zhang Hao

Hao Zhang is an Associate Professor in Department of Precision Instrument, Tsinghua University. He received a B.S. in Optical Engineering from Beijing Institute of Technology in 2006 and a Ph.D. in Optical Engineering from the same institute in 2011. He spent one-year study as a visiting Ph.D. student in Centre for Advanced Photonics and Electronics at University of Cambridge during 2009/2010. His research has been mainly focused on holography and diffractive optics, aiming for high-quality 3D diffraction fields reconstructions with his endeavors in diffraction theory, holographic algorithm, and system optimization. He has established a generalized framework for analyzing the numerical diffraction calculations based on phase space optics, which provides comprehensive representations of the diffraction fields in the joint space-frequency domain. He has also developed a series of algorithms for synthesizing 3D computer-generated holograms to provide accurate depth information of the diffraction fields, leading significant improvements of the depth performances. In addition, he has systematically investigated the mechanisms of various noises in the holographic reconstruction systems, and introduced generalized methods for suppressing speckle, conjugate, and zero-order noises, which have been widely used by researchers in related fields. He has published more than 80 peer-reviewed papers with an h-index of 23 and Google Scholar citations over 3000. He has served as a guest editor for SPIE Optical Engineering and MDPI Photonics. He is a member of SPIE, Optica, and Chinese Optical Society.
