Abstract
An eyepiece for a head mounted display includes an imaging region and a viewing region. The imaging region includes a camera. The viewing region is aligned with an eye of a user and includes a first beam splitter and a second beam splitter. The viewing region is partially transparent to pass a first portion of ambient scene light received through an ambient scene side of the eyepiece out an eye-ward side of the eyepiece. The first BS and the second BS are partially reflective and oriented to redirect offset portions of the ambient scene light received through the ambient scene side along the eyepiece towards the imaging region. The camera is positioned to capture both of the offset portions of the ambient scene light redirected by the first beam splitter and the second beam splitter.
