Abstract
An apparatus includes an illumination module, an end reflector, and a beam splitter. The illumination module launches display light along a forward propagating path within an eyepiece. The end reflector is disposed at an opposite end of the eyepiece from the illumination module and reflects back the display light traveling along a reverse propagating path. The beam splitter is disposed in the forward propagating path between the end reflector and the illumination module. The beam splitter directs a first portion of the display light traveling along the forward propagating path out a first side of the eyepiece. The beam splitter directs a second portion of the display light traveling along the reverse propagation path out a second side of the eyepiece.
