Abstract
A combiner eyepiece with an enhancement imagery source and a collimating mirror is equipped with two oblique partially reflective mirrors. Both mirrors reflect some of the light impinging on their partially reflective sides and transmit substantially all of the rest of such light. The result is a collimated beam of light travelling toward the viewer along the viewing axis and expanded in vertical extent. This expanded vertical extent eases the requirement for the viewer to place his eyes in a precise location at the near end of the eyepiece. It also allows a smaller and lighter construction for an eyepiece where the vertical extent of the viewing area has been specified.
