Light fields provide a natural way of representing the information that is captured and processed by the human visual system. Light fields can be acquired using compact imaging systems and the information can be used for a variety of applications including analysis, interpretation and display. Light field display architectures enable true 3D displays that provide a natural and comfortable experience. In both imaging and display, the system design has to consider a complex set of tradeoffs. This seminar will provide an introduction to light fields, followed by an in-depth discussion of state-of-the-art light field imaging and display systems, some interesting applications such as AR and VR and the key tradeoffs that have to be considered during the design process.
