Abstract

An optical system of a head-mounted display (HMD) system that includes a diffractive optical element coupled to a display, for example, via lamination or a suitable optically clear adhesive. The optical system may include a reflective polarizer and a quarter-wave plate that, together with the diffractive optical element, form a catadioptric or 'pancake' configuration that focuses light from a display system to an eye of a user of the head mounted display system.
