Abstract

An optical sensor and method of using the same is provided for sensing relative movement between the sensor and a surface (512) by detecting changes in optical features of light reflected from the surface. In one embodiment, the sensor includes a two dimensional array (302) of photosensitive elements (304), the array including at least a first plurality of photosensitive elements arranged and coupled to sense a first combined movement along a first set of at least two non-parallel axes, and a second plurality of photosensitive elements arranged and coupled to sense a second combined movement along a second set of at least two non-parallel axes.
