Aberration correction in holographic displays

Optical aberrations hinder the realization of high-quality near-eye displays. The imperfection of the optical components and the human eye causes image quality degradation. This invited paper introduces two recent works on aberration correction methods in holographic displays. The wave optics-based computer-generated hologram calculation method to correct the optical aberration from the eyepiece of the near-eye display is presented. In addition, the ray tracing-based vision-correcting holographic display for correcting the ocular aberration of the human eye is demonstrated.
