摘要：An optical encoder includes a code strip having a first side, a second side, a first
track comprising indicia thereon, and a second track comprising indicia thereon. The codestrip is moveable along a displacement path with respect to the optical encoder. A lightsource positioned on the first side of the code strip directs light toward the code strip. Afirst detector element is positioned on the second side of the code strip and is generallyaligned with the first track of the code strip. A second detector element is positioned onthe second side of the code strip and is generally aligned with the second track of thecode strip. The second detector element is also positioned so that the second detectorelement is located a spaced distance along the displacement path from the first detectorelement.
