Abstract: Methods and systems for indicating the displacement of a flexible web are described. An elongated, flexible web includes an integral scale having scale features configured to modulate energy directed towards the web. A transport mechanism provides relative movement between the web relative to a transducer. The transducer detects energy modulated by the scale features and generates a signal indicting a continuous web displacement based on the modulated energy.

Abstract: Methods and systems for forming a displacement scale comprising TIR prisms on a substrate are described. A system for forming the displacement scale includes one or more rollers having a pattern of total internal reflection (TIR) prism features in negative relief. As the rollers are rotated, the scale is formed on the substrate. The rollers may also include pattern features in negative relief. Rotation of the rollers simultaneously forms the displacement scale and the pattern features on the substrate. The TIR prism features of the displacement scale may be oriented to provide measurement of one or more of lateral displacement, longitudinal displacement and angular displacement.

Abstract: Methods and systems for determining the displacement of a substrate using a scale comprising TIR scale features are described. A scale that includes a number of total internal reflection (TIR) prisms as scale elements is disposed on the substrate. Light directed towards the scale is modulated by the TIR prisms. A signal indicating a displacement of the substrate is generated based on the modulated light. The signal 10 may be used to determine the web position, to control web movement, and/or to measure various web parameters.

Abstract: Methods and systems for determining longitudinal position of an elongated web are described. Sensors are used to detect one or more substantially continuous fiducial marks disposed longitudinally on the web. The sensors generate signals associated with the fiducial marks. A position detector receives the signals and determines a longitudinal position of the web using the sensor signals. The fiducial marks may be periodic fiducial marks, such as sine and/or cosine marks on the web and/or may be piecewise continuous marks. The coarse longitudinal position of the web can be determined based on periodically recurring features of the fiducial marks. The fine longitudinal position can be determined based on continuous portions of the fiducial marks between the periodically recurring features.
