This paper proposes aberration improvement technology for thin and lightweight head-mounted displays with holographic optics and polarized laser backlights. The MTF is improved by adding lens functionality to both the HOE and reflective polarizer. We also discuss realizing high ppd with large low-ppi panels because holographic optics remain thin regardless of the panel size.
