The polarizing beam splitter has a first optical axis extending from a first face of the cube toward an opposing second face of the cube and lying at an angle of 45 degrees to the cube-diagonal plane, and a second optical axis extending from a third face of the cube toward an opposing fourth face of the cube and lying at an angle of 45 degrees to the cube-diagonal plane, the second optical axis being perpendicular to the first optical axis. The device further includes an external polarizer external to the cube on the first optical axis and disposed to intercept light incident upon the first face along the first optical axis, an image source external to the cube and disposed to send a display image incident upon the third face along the second optical axis, a quarter-wave plate external to the cube and disposed to intercept a beam of light traveling along the second optical axis and passing out of the cube through the fourth face, and a mirror external to the cube and disposed to reflect light passing through the quarter-wave plate back through the quarter-wave plate and to the fourth face.

摘要： A kinoform optical element (KOE) has different surface relief heights in different zones of the kinoform surface, in order to optimize the first order diffraction efficiency in each zone. By increasing the first order diffraction efficiency, noise as well as ghost image problems may be reduced and contrast and resolution may be enhanced. In an exemplary embodiment, each zone, or even different areas of the same zone, has a non-constant step height that is preferably defined by a predetermined relationship between an optimal step height and an associated predominant angle of incidence associated with that particular zone or area. In the case of an optical system having a relatively large aperture and a relatively narrow field of view, each point of the KOE sees the entire image; the associated predominant angle of incidence at that point may be defined by a so-called "marginal" ray from the center of the entire image space (i.e., on the optical axis and at the effective "middle" of the usable depth of field). In the case of an optical system having a relatively small aperture and a relatively wide field of view , each point of the KOE sees only a portion of the image; the associated predominant angle of incidence at that point may be defined by an exemplary ray from the portion of the image space that is visible from that point. Since the optimum surface relief is dependent on the angle of incidence of the radiation relative to the orientation of the surface, diffraction efficiency can also be optimized by providing the kinoform with a non-planar surface contour such that all the predominant rays are normal to the active surface, in which case all the steps may have the same height.
摘要翻译： Kinoform光学元件（KOE）在kinoform表面的不同区域中具有不同的表面浮雕高度，以便优化每个区域中的一阶衍射效率。通过增加一级衍射效率，可以降低噪声以及重影图像问题，并且可以提高对比度和分辨率。在示例性实施例中，相同区域的每个区域或甚至不同区域具有非恒定台阶高度，其优选地由最佳台阶高度与与该特定区域相关联的相关联的主要入射角之间的预定关系限定，或区。在光学系统具有相对较大的光圈和相对较窄的视野的情况下，KOE的每个点看到整个图像; 在该点处的相关联的主要入射角可以通过从整个图像空间的中心（即，在光轴上和在可用景深的有效“中间”）的所谓“边缘”射线来定义，。在光学系统具有相对小的孔径和相对宽的视场的情况下，KOE的每个点仅仅看到图像的一部分; 可以通过从该点可见的图像空间部分的示例性射线来定义在该点处的相关联的主要入射角。由于最佳表面浮雕取决于辐射相对于表面的取向的入射角，所以衍射效率也可以通过提供非平面表面轮廓的kinoform来优化，使得所有主要的光线垂直于活动表面，在这种情况下，所有步骤可能具有相同的高度。
