摘要： An apparatus for simultaneously imaging a subject and displaying computer generated image (“CGI”) light to the subject includes a display array and a photodetector array. The display array and the photodetector array are disposed on a same semiconductor die. The display array includes display pixels configured to selectively generate the CGI light to be sent along a forward optical path. The photodetector array is positioned to receive non-visible image light that is reflected by the subject and directed along a reverse optical path. The CGI light to be sent along the forward optical path travels in a substantially opposite direction as the non-visible image light directed along the reverse optical path.

摘要： An eyepiece for a HMD includes a waveguide, an ambient light polarizer, and a wire grid polarizer with a diffraction lens having a lens function patterned into the wire grid polarizer. Polarized image light is guided between eye-ward and ambient sides of the waveguide from a display source to a viewing region of the waveguide where the polarized image light is directed out of the waveguide through the eye-ward side. The viewing region passes ambient light incident on the ambient side through to the eye-ward side. The ambient light polarizer is disposed adjacent to the ambient side to polarize the ambient light into polarized ambient light having a second polarization orthogonal to the first polarization. The wire grid polarizer is disposed adjacent to the eye-ward side along the viewing region. The wire grid polarizer is oriented to applying the lens function to the polarized image light via diffraction.
