Curved waveguide combiner for head-mounted and helmet-mounted displays (HMDS), a collimated virtual window, or a head up display (HUD)

摘要

A head mounted or helmet mounted display (HMD), head up display (HUD, or collimated virtual window can be used in various applications including but not limited to avionic applications. The HMD, HUD, or collimated virtual window can include a cylindrical, elliptical, or curved substrate waveguide combiner. The cylindrical or curved substrate waveguide combiner can be used with a projector which provides pre-aberrated light. The cylindrical substrate waveguide combiner provides collimated light to a user with reduced wavefront errors.
