Abstract
We propose a novel mechanically scanned B‐scan system for imaging the interior of solids with diffraction‐limited resolution. By utilizing an additional spherical surface in conjunction with a conventional acoustic lens, it is possible to reduce spherical aberration, (which would otherwise seriously degrade the imaging performance), to a negligible value. In typical situations, it is possible to scan the focus through a depth of several hundred wavelengths.Keywords
