Abstract
Two dimensional encoder system and method designed to improve accuracy, compactness, stability, resolution, and/or light efficiency of metrology carried out with such system and method. Embodiments employ a novel retroreflector which while particularly useful in present invention, is believed to have more general utility in optical imaging systems and methods.
