Abstract
Optical encoding systems include a generalized cylindrical code scale having one or more regions with different light reflective properties. In an example process, a code scale can be created by coating an elongated generalized cylinder with one or more different layers of materials having different light reflective properties. Portions of these layers can be removed selectively in order to expose a particular overlying material and create a particular pattern of features having different optical characteristics (e.g., absorbing, specularly reflecting, diffusely reflecting).
