内  容：In-vivo imaging of the human retina with high resolution is important for both basic science and clinical patient care; but it has been confronted by a host of obstacles. First of all, the light can be used for imaging is extremely weak duo to low reflectance and numerical aperture of the human eye as well as the safety constraint. Secondly, it is difficult to optimize image contrast duo to tissue scattering in the lens, vitreous and retina as well as absorption of light by the cornea and lens, particularly in the diseased or the aging human eye. Therefore, the retinal imaging system must be of high efficiency in light illumination and collection.

Biography

Yuhua Zhang received his bachelor degree from Tianjin University, China in 1986, majoring in precision instruments engineering. Then he worked 4 years in industry as a metrology engineer. He received his master degree majoring in optical engineering from the graduate school of Chinese Sciences Academy, Changchun Institute of Optics, Fine Mechanics and Physics in 1993. He completed doctoral studies in precision metrology and instruments engineering at Tianjin University where he received the PhD in 1997. Dr. Zhang had post-doctoral training in adaptive optics in Beijing Institute of Technology (1999), and worked in Shanghai Jiaotong University as an associate professor. As an academic research fellow, he continued his research in adaptive optics in Auckland University, New Zeland (2002), and did research on optical coherence tomography in the University of West Australia, Perth, Australia (2003). In August 2003, he joined the lab of Austin Roorda, PhD, at the College of Optometry, University of Huston, TX. In 2004, he moved to University of California at Berkeley, where he assumed the academic position of Assistant Researcher (UC research academic position parallel to assistant professor) Now，Dr. Zhang is a member of ARVO, OSA, SPIE and ISER. He was a recipient of the R&D 100 Awards in 2007 for the development of the Micro-Electrical-Mechanical System (MEMS) based adaptive optics scanning laser ophthalmoscope along with the researchers at the University of California at Berkeley, the University of Rochester, Indiana University and Lawrence Livermore National Lab.
