摘要： An optical stack (400) having a plurality of alternating polymeric layers (401, 402) is described. The alternating layers may be alternating birefringent (syndiotactic polystyrene, sPS) and isotropic (CoPENa) layers, or alternating positively and negatively birefringent layers. Birefringent layers are made using polymers which form optically symmetrical crystallites upon stretching of the polymer. The optical stack has a large refractive index difference in the x- direction (the stretching direction) and small refractive index differences in the y- and z-directions (the non - stretching directions). The optical stack can be made using standard film tentering methods and may be a multilayer reflective polarizer.
摘要翻译：描述了具有多个交替聚合层（401,402）的光学堆叠（400）。交替层可以是交替的双折射（间同立构聚苯乙烯，sPS）和各向同性（CoPENa）层，或交替的正负双折射层。使用在聚合物拉伸时形成光学对称微晶的聚合物制备双折射层。光学堆叠在x方向（拉伸方向）上的折射率差大，y方向和z方向（非拉伸方向）的折射率差小。光学堆叠可以使用标准薄膜拉制方法制成，并且可以是多层反射偏振器。

摘要： A light diffusing optical construction is disclosed. The optical construction includes a symmetric optical diffuser that scatters light in a first direction with a first viewing angle A H and in a second direction orthogonal to the first direction with a second viewing angle A V , where A V is substantially equal to A H . The symmetric optical diffuser includes an optically transparent first layer and a plurality of randomly arranged optically transparent beads partially embedded in the first layer leaving portions of the beads exposed. The optical construction also includes a specular reflector that reflects light that is not scattered by the symmetric optical diffuser. The specular reflector has a first average reflectance R o in the visible at zero incident angle and a second average reflectance R 60 in the visible at 60 degree incident angle. R o /R 60 is at least about 1.5. The optical construction also includes a light absorbing layer that absorbs light that is not reflected by the specular reflector.

摘要： A projection system is disclosed. The projection system includes a projector that sequentially emits first images having a first polarization state for viewing by a left eye and second images having the first polarization state for viewing by a right eye. The projection system further includes a front projection screen that scatters the sequentially emitted first and second images. The front projection screen reflects light having the first polarization state, and absorbs light having a second polarization state, where the second polarization state is perpendicular to the first polarization state. The projection system also includes a viewing device that includes a first shutter that is synchronized with the projector and transmits the first, but not the second, images scattered by the front projection screen. The viewing device also includes a second shutter that is synchronized with the projector and transmits the second, but not the first, images scattered by the front projection screen. Each of the first and second shutters has a pass axis that lies along the first polarization axis and a block axis that lies along the second polarization axis.
