Abstract
Encoder systems provide measurement and reference optical paths based on propagation in a common set of optical elements along paths that are displaced angularly or spatially. Associated measurement and reference beams are reflected by corner cubes to as to define first paths and second paths. The measurement and reference beams are combined to determine a work piece displacement in a manufacturing process.
