The above flowchart shows
the process of dot images generated in the infrared spectrum and recorded
before and after deformation which allows in-plane and out-of-plane strains
to be obtained in soft materials, in biological tissue. The technique is non-contacting and
non-invasive and is based on the principles of geometric moiré and fringe
projection. Some typical raw data is
available in a video clip and processed results. For more information on
the technique: HEREDIA

thermal marking’, Strain, 39:149-152. |
