Abstract
A head-mounted display includes an electronic display configured to output image light, an optics assembly configured to direct image light in a first band from the electronic display to an eye box, an eye tracking unit configured to generate eye tracking information, and a beamsplitter configured to redirect light in a second band reflected from the eye box toward the eye tracking unit and transmit the image light in the first band. The beamsplitter includes a first region and a second region, and a first portion that joins the first region and the second region is curved such that an angle between the first region and the optical axis is larger than an angle between second region and the optical axis, and the beamsplitter is positioned along the optical axis between the optics assembly and the electronic display.
