摘要： An integrated vision and display system comprises a display-image forming layer configured to transmit a display image for viewing through a display surface; an imaging detector configured to image infrared light of a narrow range of angles relative to the display surface normal and including a reflection from one or more objects on or near the display surface; a vision-system emitter configured to emit the infrared light for illuminating the objects; a visible- and infrared-transmissive light guide having opposing upper and/or lower face, configured to receive the infrared light from the vision-system emitter, to conduct the infrared light via TIR from the upper and lower faces, and to project the infrared light onto the objects outside of the narrow range of angles relative to the display surface normal.

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.

摘要： The present invention provides an apparatus and a method for reshaping the best focus surface to more closely match the surface geometry of a nonplanar surface, such as a sphere. The apparatus includes a complex phase plate located between a mask for generating an image and an elliptical mirror. The mirror has a unique wavefront error and an aspheric image focus surface which is corrected by the complex phase plate, thereby shifting the focus surface to correspond to the nonplanar surface. The apparatus may be used for various shaped substrates, such as a spherical shaped semiconductor device. The complex phase plate includes a variable focal length optical element. The variable focal length optical element may include a diffractive optical element with a plurality of complex phase grating sections repeated over a surface of thereof, located in immediate proximity to the mask.
