Title: Observed optical resolution of light field display: Empirical and simulation results [SD&A-391]
Speaker: Yuta Miyanishi, Tampere University (Finland)
Abstract: Light field (LF) displays are a promising 3D display technology to mitigate the vergence-accommodation conflict. Recently, we have proposed a simulation framework to model an LF display system. It has predicted that the in-focus optical resolution on the retina would drop as the relative depth of a rendered image to the display-specific optical reference depth grows. In this study, we examine the empirical optical resolution of a near-eye LF display prototype by capturing rendered test images and compare it to simulation results based on the previously developed computational model. We use an LF display prototype that employs a time-multiplexing technique and achieves a high angular resolution of 6-by-6 viewpoints in the eyebox. The test image is rendered at various depths ranging 0–3 diopters, and the optical resolution of the best-focus images is analyzed from images captured by a camera. Additionally, we compare the measurement results to the simulation results, discussing theoretical and practical limitations of LF displays.
Biography: Yuta Miyanishi received his B.E. degree in computer science and M.S. degree in human centered science and biomedical engineering from Tokyo Institute of Technology in 2016 and 2018, and he is currently pursuing his doctoral degree at Tampere University in Finland. After his study on stereopsis in a psychophysical approach at Tokyo Tech, he is now involved in theoretical and empirical research on light field displays and human observers.
