Paper Abstract

In this paper we introduce a method allowing theoretical calculation of linearity and scale factor errors in linear position sensors based on bi-cell photodiodes. Such calculations are applied using three methods to compensate for scale factor temperature drift. An example based on data of a specific sensor was computed to illustrate how the sensor's dimensions and drift compensation method influence the scale factor and linearity errors of its volt-displacement characteristic.
