    • A system for directing light in an interactive display system so as to perform multiple functions. In addition to projecting images on the interactive display system, the system is used to distribute infrared (IR) light onto the display surface, and/or to receive and focus received IR light reflected from a physical object on the display surface. A light separating system separates a multi-waveband light from a source into a predominantly visible light and a predominantly non-visible light, the latter being redirected around visible light modulators and recombined with the modulated visible light for projection onto the display surface by a lensing system. In addition, or in the alternative, the light separating system separates predominantly non-visible light reflected from an object adjacent to the surface, from light produced by the source, directing only the non-visible light received to the light sensor used to image the display surface.
    • 一种用于在交互式显示系统中引导光以便执行多种功能的系统。 除了在交互式显示系统上投影图像之外,系统还用于将红外(IR)光分布到显示表面上,和/或接收和聚焦从显示表面上的物理对象反射的接收到的红外光。 光分离系统将来自源的多波段光分离成主要可见的光和主要是不可见的光,后者被重新定向在可见光调制器周围,并与调制的可见光重新组合,用于通过透镜来投影到显示表面上 系统。 此外,或者在替代方案中,光分离系统主要从与表面相邻的物体反射的不可见光从光源产生的光分离,仅将接收到的不可见光引导到用于对 显示表面。
