Wide field of view occlusion capable augmented reality pancake optics head mounted display

Abstract:

Embodiments provide for a display system that overlays augmented reality (AR) content onto a view of an environment. The display includes a first polarizer that receives light providing a view of the environment (which can be natural light or light generated from another display). The polarized light then passes through a transparent display that emits light forming the AR content. The light emitted by the display and the polarized light of the environment pass through a beam splitter before reaching a selective mirror. The polarized light from the environment passes through the selective mirror while the light from the display is reflected back towards the beam splitter where it is collimated. Moreover, when collimating the light, the beam splitter also reflects the light back towards the selective mirror and changes its polarization so the light can pass through the selective mirror.
