Measurement of uncertainty in orientation distribution function calculations

A technique to quantify the uncertainty in an estimated orientation distribution function (ODF) by propagating the uncertainty from measured pole figures is demonstrated in this paper using Monte Carlo techniques and the Matlab toolbox for quantitative texture analysis. Unlike the uncertainty in the measured pole figures, where small values of intensity correlate to high uncertainty, uncertainty as a function of orientation in an ODF is not directly related to intensity.
