Abstract

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 (see figure 3). The sensor includes at least an illuminator (306), telecentric imaging optics for example, (see figure 5, 502 or 504) on the object (scattering surface) side, and an array of photosensitive elements (302). The illuminator (306) is configured to illuminate a portion of the surface (402). The telecentric imaging optics (see figure 5, 502 or 504) is configured to image the optical features emanating from the illuminated portion of the surface (see figure 4, 402), and the array of photosensitive elements (302) is configured to detect intensity data relating to the optical features imaged by the telecentric imaging optics (see figure 5, 502 or 504).
