Abstract

We report a compact, yet high ambient contrast ratio augmented reality system by incorporating a tunable transmittance liquid crystal cell and a thin reflective polarizer. Moreover, if we replace the reflective polarizer with a functional reflective polarizer, the system would benefit those users with color vision deficiency.
