Abstract

Three-dimensional light field displays are not yet widely adopted due to the bulky form-factor and limited image quality caused by optical aberrations of microlens arrays (MLAs). Conventional optimization techniques cannot approach the maximal displayed image quality as they rely on intermediary metrics such as focal spot size. In order to optimize for the full-color wide field-of-view image quality, the point spread function of the MLA should be modeled to provide more flexibility. We developed a modeling approach for both refractive and metasurface MLAs and assessed the accuracy by judicious comparisons between the numerical simulations and experimental characterization.
