    Abstract: A near-eye display device includes (a) a display unit for displaying a display image, (b) a viewing unit for presenting the display image to the eye and transmitting ambient light from an ambient scene toward the eye, and (c) an eye imaging unit including (i) an illumination module for generating at least three infrared light beams propagating along at least three different, non-coplanar directions, respectively, (ii) a first beamsplitter interface, disposed between the display unit and the viewing unit, for merging at least a portion of each of the infrared light beams with visible display light to direct each portion toward the eye via the viewing unit, and (iii) a camera for imaging, via the viewing unit and the first beamsplitter interface, pupil of the eye and reflections of the infrared light beams incident on the eye, to form one or more images indicative of gaze direction of the eye.

    Abstract: A lensed beam-splitter prism array includes a beam-splitter substrate with a plurality of planar and parallel thin-film coatings each spanning a top substrate surface and a bottom substrate surface, and making an oblique angle therebetween, and a lens form layer formed on the top surface and having a plurality of lens forms, each lens form being above one of the plurality of coatings. A method for fabricating a lensed beam-splitter prism includes bonding a plurality of substrates to form a substrate stack having a coating between each adjacent substrate pair. The method also includes forming a stack slice by applying a plurality of parallel cuts at an oblique angle with respect to each coating. Each coating spans a first stack-slice surface and a second stack-slice surface opposing the first stack-slice surface. The method also includes forming a lens form layer on the first stack-slice surface spanning one or more coatings.
