Among the different optical measurement techniques for full-field
analysis of displacements and strains, digital image correlation
(DIC) has proven to be very flexible, robust, and easy to use, covering
a wide range of different applications. DIC measurement results,
among others, are influenced by the systematic errors of the measurements
system, a major source of which is due to imaging system calibration.
We present a 3-D DIC system that provides online error information
concerning diverse error sources, and even more important, the propagation
of errors throughout the calculations to the resulting contours,
displacements, and strains. On the basis of this system we discuss
error sources, error propagation, and the impact on correlation results.
Performance tests for studying the impact of calibration errors on
the resulting data are shown for static and dynamic applications.
