System, method, and non-transitory computer-readable storage media related wearable pupil-forming display apparatus with variable opacity and dynamic focal length adjustment
A wearable display apparatus has an image generator that is energizable to form a 2D image; a partially transmissive mirror having a curved reflective surface; a beam splitter disposed to reflect light toward the curved mirror surface; and an optical image relay that is configured to relay the formed 2D image at the image generator to a curved focal surface of the partially transmissive mirror, wherein the curved focal surface is defined between the curved reflective surface of the partially transmissive mirror and the beam splitter, wherein the relay, curved mirror, and beam splitter are configured to form an exit pupil for viewing the generated 2D image as an optical virtual image; and a spatial light modulator configured with addressable array of pixels for selectively changing opacity for visible light from the object field according to dimensions of the generated 2D image.
