发明名称 Two dimensional encoder system and method
摘要 An encoder system and method are provided, that is designed to improve 2D encoder systems and methods in areas such as accuracy, compactness, stability, resolution, and/or light efficiency. Moreover, the system and method of this invention provides a new concept in a retroreflector that while particularly useful in applicants' system and method, is believed to have more general utility in optical imaging systems and methods.
