Abstract
An investigation is made of the effects of using high numerical aperture acoustic lenses on the V(z) respsonse in acoustic microscopy. Theoretical results are presented for a perfectly reflecting object in an aplanatic system and show marked differences from the paraxial predictions. This suggests that for accurate determination of surface elastic parameters the effects of high angles of convergence should be taken into account.Keywords
