Abstract of the Disclosure A cursor position control system in which an optical mouse having a light source and three-by-three detector array moves over a surface having a grid pattern of intersecting orthogonal grid lines of a first color and spaces defined between the grid lines of a second contrasting color. The grid lines are characterized by a line width. Detector cells are grouped into pairs of cells for detecting motion in a particular direction. Cells in a pair are separated so as to image areas an odd multiple of line widths apart in a direction orthogonal to that particular direction. Pairs of cells image areas separated in the particular direction from areas imaged by related pairs of cells by an odd multiple of half line widths. Pairs of electrical signals from pairs of cells are combined then differentiated with respect to time to produce related quadrature signals indicative of the amount and direction of movement of the mouse relative to the surface.
