A high-resolution optical position encoder is described that consists of a scale as encountered in a standard moiré-based system, a simple imaging system with stabilized magnification and a novel segmented phase detector integrated circuit. Compared with encoder systems of comparable resolution and accuracy, the encoder presented offers large mechanical… CONTINUE READING
