Abstract
Light field displays comprise three-dimensional (3D) visual information
presentation devices capable of providing realistic and full parallax
autostereoscopic images. In this letter, the recent advances in the light field
displays based on integral imaging (II) and holographic techniques are presented.
Several advanced approaches to demonstrate the light field displays including
viewing angle enhancement techniques of the II display, a fast hologram generation
method using graphics processing unit (GPU) and multiple WRPs, and a holographic
microscopy to display the living cells are reported. These methods improve some
important constraints of the light field displays and add new features.
