    Abstract: The present invention provides an optical device comprising: (a) a substrate; and (b) a plurality of units on the substrate. Each of the units comprises a plurality of tapered waveguides wherein: (i) each of the waveguides has a light input surface adjacent the substrate (a) and a light output surface distal from the light input surface and the light input surface area is greater than the light output surface area; (ii) each of the waveguides tapers from its light input surface to its light output surface at an angle; and (iii) at least one of the light input surface area or the light output surface area of at least one of the tapered waveguides is different than the corresponding surface area of the remaining tapered waveguides in the unit. Preferably, the optical device is a viewing film. The present viewing film has reduced or substantially eliminated intensity hot spots and interference patterns. The present viewing film may be used in display devices, such as for example projection display devices, off screen display devices, and direct view displays. Such displays are used in a wide range of applications including computer terminals, airplane cockpit displays, automotive instrument panels, televisions, and other devices which provide text, graphics, or video information.

    Abstract translation: 本发明提供了一种光学装置，包括：（a）基板; 和（b）基板上的多个单元。 每个单元包括多个锥形波导，其中：（i）每个波导具有与基板（a）相邻的光输入表面，远离光输入表面的光输出表面和光输入表面积大于 光输出面积; （ii）每个波导以一定角度从其光输入表面到其光输出表面渐缩; 和（iii）至少一个锥形波导的光输入表面区域或光输出表面区域中的至少一个不同于单元中剩余的锥形波导管的相应表面积。 优选地，光学装置是观察膜。 本观看膜具有减少或基本消除的强度热点和干涉图案。 本观看膜可以用于显示装置，例如投影显示装置，离屏显示装置和直视图显示器。 这种显示器用于广泛的应用，包括计算机终端，飞机驾驶舱显示器，汽车仪表板，电视机以及提供文本，图形或视频信息的其它设备。
