Noncontact Infrared Imager

The ALTAIR Li system provides top quality images of stress in materials and structures under dynamic, transient or random loading conditions. The ALTAIR Li uses and IR camera that provides thermal images of the area under investigation at fast frame rate. These thermal images are converted into full field stress images without any contact with the material surface. The full field stress images are produced in real time by using the thermoelastic effect. The ALTAIR Li is used for applications including stress measurement, fatigue limit testing, thermo-mechanical studies and damage prediction experiments.
