报告摘要：

Strong light scattering can make even an optically non-absorbing object opaque preventing deep light penetration. Many far-reaching applications, such as deep brain imaging could benefit from a better coupling of light into scattering medium and increased penetration depth resulting into greater transmission through a highly scattering medium. In this talk I will present a simple, but efficient way of increasing light coupling through optical interface engineering. Capitalizing on our prior work [1-6], we provide a theoretical foundation for our experimental findings and discuss potential applications for imaging and sensing [7-8].

He got his PhD in 1990 from Moscow State University. After a short stay with Novatec Laser System, Inc., where he discovered what is now known as bladeless LASIK, he worked in the Department of Chemistry and Biochemistry at UCSD as a postdoctoral researcher and research scientist developing new tools for optical molecular spectroscopy, imaging and control. Dr. Yakovlev started as an assistant professor at the University of Wisconsin – Milwaukee in 1998 and moved to Texas A&M University in 2011. He has more than 150 research publications in leading scientific journals. His research was supported by NSF, NIH, ARO, AFOSR, ONR, and DARPA. Dr. Yakovlev is a Fellow of OSA, AIMBE, APS and SPIE. He is a member of Editorial Board of Journal of Biomedical Optics, Optica and Applied Sciences. His research interests are in a broad area of optical spectroscopy, microscopy, imaging and sensing.
