Chapter 3

Measurement and Monitoring of the Accuracy of Scales and Encoders

The use of linear and circular raster scales for length and angle measurements are first discussed. Traditional methods for angular scales calibration using various angle reference standards are reviewed and some new methods for circular scales calibration are then introduced, including the use of Moiré and Vernier fringe patterns.

The measurement of linear scales and transducers are then discussed and comparators for the calibration of linear standards are described. This is then extended to comparators for angular standards, including the application of piezoelectric actuators for angular rotation. A multipurpose test bench for angle calibration is introduced.
