Abstract
A generator structure has alternating linear regions which are respectively relatively absorbing and relatively non-absorbing. When the structure is illuminated, the spatial contrast in the absorption created by the characteristics of the regions gives rise to mechanical effects within the workpiece, such as localized heating. This results in ultrasound being created to propagate through the workpiece.
