Abstract: We investigate the optical characteristics of scattering medium by employing the pseudospectral time-domain (PSTD) simulation technique. We model continuous-wave (CW) light propagation through scattering media. We show that with specific amplitude and phase, light can propagate and focus through scattering media. Specifically, we explore the feasibility of focusing light through a scattering medium with incomplete information of the amplitude and phase. Research findings may shed light to enhancing the effectiveness of light propagation through scattering medium.
Biography: Snow H. Tseng received a B.S. degree in physics from National Taiwan University, Taipei, Taiwan, in 1994; a M.S. degree in physics from University of Chicago, Chicago, IL. in 2001; and a Ph.D. degree in electrical engineering at Northwestern University, Evanston, IL. in 2005. Beginning in 2006, he joined the Graduate Institute of Photonics and Optoelectronics and Department of Electrical Engineering of National Taiwan University as an assistant professor. In 2010, he was promoted to an associate professor. Based upon rigorous solutions of Maxwell’s equations using the pseudospectral time-domain (PSTD) technique, his general research interest is in the optical interactions of biological tissues and electromagnetic wave propagation in random media. In recent years, he has devoted his attention to exploring the possibility to enhance delivery of light deeper into biological tissues to help furtherance of biomedical optics techniques.
