摘要： A display screen for projected images can act as a touch screen through use of IR sources with homogenizers to create an area of illumination in a plane parallel to and adjacent the screen surface. The presence of a finger or pointer reflects a portion of the illumination to a detector remote from the screen. The detector is capable of identifying the x-y location on the screen of the light spot being detected. In an alternative embodiment in which the use of a finger or other pointing device is impractical, a laser pointer, equipped with an IR source, projects a light spot on the screen whose x-y location can uniquely be determined by the detector device.

摘要翻译： 用于投影图像的显示屏可以通过使用具有均匀器的IR源作为触摸屏，以在与屏幕表面平行并相邻的平面中产生照明区域。 手指或指针的存在将照明的一部分反射到远离屏幕的检测器。 检测器能够识别被检测的光斑的屏幕上的x-y位置。 在手指或其他指示装置的使用不切实际的替代实施例中，配备有IR源的激光指示器在屏幕上投射光点，其中x-y位置可以由检测器装置唯一地确定。

摘要： A compensated higher order waveplate is constructed of substrates. In one embodiment, a first substrate is a nlambda waveplate and the second substrate is a (n+ Delta )lambda waveplate. The substrates are oriented so that their principle axes of retardation are orthogonal. nlambda, is a base retardation of a waveplate and Delta lambda, is an incremental retardation. The incremental retardation produces a desired amount of retardation of a lightwave passing through the compensated higher order waveplate. Retarder material used to produce the base retardation is approximately ½ a desired thickness of the waveplate. Multiple waveplates are combined to produce any of wavelength band specific retarders and multiple non contiguous wavelength band specific retarders.
