Pupil matched occlusion-capable optical see-through head-mounted display

An occlusion-capable optical see-through head-mount display (OCOST-HMD), comprising:

• a polarizer to produce polarized light associated with a real scene;
• a beam splitter (PBS);
• an objective lens;
• a spatial light modulator (SLM);
• an eyepiece lens;
• a retarder;
• a microdisplay;
• and
• a half-mirror configured to reflect substantially all of light associated with an occlusion mask that is incident thereupon in a first direction, and to transit substantially all of light associated with a virtual scene that is incident thereupon from a second direction, wherein
• the PBS is positioned to:
• receive and direct the polarized light toward the SLM,
• receive and direct the light associated with the virtual scene toward a position for viewing by a user's eye, and
• receive and direct the light associated with the occlusion mask toward the half mirror, wherein the occlusion mask corresponds to a virtual image presented on the microdisplay
• the SLM is configured to modulate the light incident thereon in accordance with a two-dimensional shape of the occlusion mask, and
• the OCOST-HMD is configured to produce an erect image, and the position of a user's pupil, or relayed pupil, is mapped to the position of the user's eye to enable a correct view point disparity to be maintained.
