A prism eye piece and optical system including a prism eye piece and microdisplay are described herein. The prism eye piece may include three prisms. A main body prism has a surface that receives light from a source such as a microdisplay. Another prism has a surface that receives light from a source such as the real world. Both of these images are projected through a surface of still another prism that is proximate to an exit pupil. The surface of the prism proximate the exit pupil may be flat. Also the surface of the prism that receives light from a source such as the real world may be flat. These flat surfaces may be parallel to each other. This allows the light from the real world to be transmitted to the exit pupil without distortion. |
