Abstract
Compact and low mass augmented and fully virtual head mounted display designs are disclosed. The disclosed displays employ a display located between the eye and the main optical element of the head mounted display. These designs additionally afford the ability to support augmented reality displays because the user can see both the virtual image from the display and the real world if desired. The designs use semi-transparent displays where either the display emits circularly polarized light or the displays which emits light from one surface or the view of the display directly from the eye is obscured.
