Improving the Stability and Linearity of a Coordinate Characteristic of Scanistor Information and Measuring Systems

Abstract

The paper deals with issues of increasing the accuracy of the geometrical parameter measuring of objects with scanistor information and measuring system by improving stability and linearity of the coordinate characteristics. Measures to reduce its temperature drift are described. It is shown that the measurement error arising because of the coordinate characteristic nonlinearity can be reduced by correcting the form of a scanning voltage, introducing correction data to the measurements, or decreasing the nonlinearity of bleeder bar resistance using some technological methods.
