Abstract

One embodiment relates to an optical displacement sensor for sensing movement of a data input device across a surface by determining displacement of optical features in a succession of frames. The sensor includes at least an illuminator, telecentric imaging optics on the object (scattering surface) side, and an array of photosensitive elements. The illuminator is configured to illuminate a portion of the surface. The telecentric imaging optics is configured to image the optical features emanating from the illuminated portion of the surface, and the array of photosensitive elements is configured to detect intensity data relating to the optical features imaged by the telecentric imaging optics. Other embodiments are also disclosed.
