Abstract
Abstract Crosshole Sonic Logging Tomography (CSLT) is an emerging innovative measurement system which provides information on the size, shape, and orientation of defects in a bored pile. In this paper, we quantify measurement precision of the CSTL system by a gage repeatability and reproducibility (R&R) study, in order to understand and model the effects of the test operators, defects, and the test machines on measurement error. We do this by setting up a test pile with three know defects and performing various measurement experiments. We use a feature extraction method to quantify measurement error. Overall, we find that the CSLT has satisfactory repeatability and reproducibility for practical usage of defect detection.
