Tempo 2D

UHF_Thin@3x    Multi-component

The multi-component laser receiver is capable of simultaneously measuring two components of the surface displacement, the out-of-plane and the in-plane motions, using a single laser probe and a single collecting optic. The detection of the in-plane component allows efficient detection of shear waves, particularly when the direction of ultrasounds propagation is normal to the surface of inspection.

History

The TEMPO 2D was born of a research and development grant awarded by the National Science Foundation. The optical setup is based on the TEMPO 1D but with a customized linear array photo-detector capable of detecting both the in-plane and out-of-plane contributions of the surface displacement. The system is capable of reconstructing the complete ultrasonic field.
