Abstract

An integral-imaging based light field head-mounted display, which typically renders a 3D scene by reconstructing the directional light rays apparently emitted by the scene via an array optics, is potentially capable of rendering correct or nearly correct focus cues and therefore solving the well-known vergence-accommodation conflict problem plaguing conventional stereoscopic displays. Its true 3D image formation nature, however, imposes significant complications and the well-established optical design process for conventional head-mounted displays becomes inadequate to address the design challenges. To our best knowledge, there are no existing methods or framework that have been previously proposed or demonstrated to address the challenges of modeling and optimizing an optical system for this type of display systems. In this paper, we present novel and generalizable methodology and framework for designing and optimizing the optical performance of integral-imaging based light field head-mounted displays, including methods of system configurations, user-defined metrics for characterizing the performance of such systems, and optimization strategies unique in light field displays. A design example is further given based on the proposed design methodology for the purpose of validating the proposed design method and framework.
