Optimized visual simulation of 3D light field display based on differentiable ray tracing

Abstract

Optimized visual simulation of three-dimensional light field display (LFD) based on differentiable parameters is presented. By introducing differentiable parameters in visual simulation of the LFD system, the gradient information are linked with error metrics can provide a foundation and guidance for optimization. The visual simulation method is further refined to support the design of more complex light-control units, which enables the simulation of composite structures composed of lens arrays and parallax barrier arrays. The optimization of LFD systems is generally confined to the analysis of either the optical characteristics of the light-control device or the quality of LFD images. An objective function is established to evaluate the display performance of the LFD system. Optical experiments verify the effectiveness of the proposed method.
