Abstract
An optical navigation device includes a casing, a circuit board, an illumination light source and an optical receiver. The casing is movably located above a navigation surface. The circuit board is disposed inside the casing. The illumination light source is disposed on the circuit board and adapted to provide an illumination channel toward the navigation surface. The optical receiver is disposed adjacent to the illumination light source. An imaging channel of the optical receiver is substantially parallel to a planar normal vector of the navigation surface, and the optical receiver is adapted to identify features on the navigation surface within a range crossed by the imaging channel and the illumination channel for providing navigation information.
