Optical measurements show 3D shifts and deformations in medical device testing

For deformation tests on acetabular shells according to ISO 7206-12 or anchoring tests of glenoid components in accordance with ASTM F2028, we use an optical measuring system instead of standard displacement transducers, which detects deformation states and strains contactlessly with maximum accuracy. This photogrammetry method measures samples and components independently of material according to the principle of digital image correlation. With an accuracy of ± 4 μm, path changes can be more flexibly and accurately recorded and visualized. We also recommend this measurement method for many other Tests.
