摘要： A light guide of the tapered-waveguide type includes an input slab for expanding a projected image between an input end and an output end, and an output slab arranged to receive rays from the said output end, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The input slab and output waveguide are matched so that all rays injected into the input end undergo the same number of reflections before leaving the output surface. With the invention, the input slab is itself tapered slightly towards the output waveguide. This means that input and output waveguides can be made the same length, in the direction of ray travel, and can therefore be folded over each other with no wasted space.
摘要翻译：锥形波导型的导光体包括用于在输入端和输出端之间扩展投影图像的输入板，以及布置成从所述输出端接收光线的输出板，并在其上的点处发射它们面对应于接收射线的角度。输入板和输出波导匹配，使得注入输入端的所有光线在离开输出表面之前经历相同数量的反射。利用本发明，输入板本身稍微朝向输出波导略微倾斜。这意味着输入和输出波导可以在光线移动方向上具有相同的长度，因此可以相互折叠而没有浪费空间。

摘要： A touch-pressure sensitive panel includes a locally and resiliently deformable waveguide having an exterior surface for receiving localized touch pressure from a user, and a wetting surface opposite the exterior surface. The panel also includes a de-wettable layer presenting a de-wettable surface arranged beneath the wetting surface, such that the localized touch pressure reversibly increases localized optical wetting of the de-wettable surface by the wetting surface. The panel also includes an imaging detector configured to receive light coupled into the de-wettable layer due to the localized optical wetting.
