Abstract
A system for calibrating an optical fiber measurement system is disclosed that can be used with deformable body parts of an anthropomorphic test device. The system includes a deformable body part and an optical fiber that has a plurality of grating sensors between first and second ends is supported about the deformable body part to generate optical strain data. The deformable body part is loaded into a testing fixture and a load is applied. At least one camera is positioned toward the testing fixture to record the deformable body part as the load is applied thereto and to capture images generating image deformation data for comparison with the optical strain data to determine a correlation, or correction, factor for the optical fiber and the body part.
