Digital image correlation (DIC) is a full-field, non-contact 3D optical technique for measuring contour, deformation, vibration and deformation in almost any material. The technique can be used with many tests, including traction, torsion, bending and combined load tests for static and dynamic applications. Digital image correlation is becoming a reliable instrument for measuring deformation and deformation in aerospace testing. A test sample is painted with dots, cameras record how the dots move when loads are applied, and the software correlates these images to produce full-field deformation or deformation data.

Who digital health guidelines?
The scarcity of evidence in digital health requires that the global digital health community adopt a more deliberate and coordinated approach to identifying and addressing gaps in research, perhaps as part of a global plan of action guided by the needs of different stakeholders, mainly ministries of health. The Digital Health Guidelines followed the WHO framework from evidence to decision7 and systematically took advantage of existing evidence and expert opinions on nine emerging priority digital innovations aimed at strengthening health systems.
