Abstract
In embodiments, a pen digitizer includes a light source that generates light. The pen digitizer also includes light guides, such as fiber optics, configured coaxial within the pen digitizer to transfer the light from the light source and focus the light around an imaging tip of the pen digitizer. A photo array optically-images reflected light from encoded bits in an encoded micro pattern, and a lens focuses the reflected light onto the photo array.
