Abstract

With the invention of integral imaging and parallax barriers in the beginning of the 20th century, glasses-free 3D displays have become feasible. Only today -more than a century later- glasses-free 3D displays are finally emerging in the consumer market. The technologies being employed in current-generation devices, however, are fundamentally the same as what was invented 100 years ago. With rapid advances in optical fabrication, digital processing power, and computational perception, a new generation of display technology is emerging: compressive displays exploring the co-design of optical elements and computational processing while taking particular characteristics of the human visual system into account. In this talk, we explore modern approaches to glasses-free 3D display using compressive light field displays. In contrast to conventional display technology, these systems aim for a joint-design of the display optics and computational processing - a concept that has been exploited for image capture in computational photography for about a decade.
