<p>Head- mounted display with an eye- tracking system and including a light transmitting substrate (20) having two major surfaces and edges , optical means for coupling light into said substrate (20) by total internal reflection, partially -reflecting surfaces (22a- 22c) carried by the substrate (20) that are not parallel with the major surfaces of the substrate (20) , a near- infrared light source (78) and a display source (92) projecting within the photopic spectrum , wherein light from the light source (78) and light from the display source (92) are coupled into the substrate (20) by total internal reflection.</p> |
