• Characteristics and Application of "Smart" Shaft Encoders

      Breslow, Donald H.; Litton Industries (International Foundation for Telemetering, 1988-10)
      A family of absolute optical shaft encoders has been configured which is based upon an electro-optical multiplexing architecture. When interfaced to a microprocessor, the resulting "smart" encoder can perform several allied data processing functions and can replace many types of electro-mechanical components. Encoder architecture, interfacing, and several allied signal processing examples are discussed.
