Abstract:
Embodiments of an apparatus comprising a CMOS image sensor including a pixel array formed in a substrate and a light guide formed on the substrate to receive light traveling in a plane parallel to a plane of the pixel array and incident on the edge of the image sensor and to re-direct the incident light into at least one pixel of the pixel array. Embodiments of an optical touch-screen imager comprising a substantially planar touch area and a detector positioned adjacent to the touch area, the detector comprising a CMOS image sensor as described above.
