Abstract

This letter reports the development of a mechanically scanned acoustic microscope showing 10‐μm resolution. Using single‐surface lenses an acoustic beam is focused with negligible spherical aberration in a water cell. The image is formed by mechanically scanning an object through this focused beam in a raster pattern. Transmitted power is detected with a piezoelectric transducer, and this signal modulates the synchronized raster of a CRT display. By employing piezoelectric detection, sensitivities of 10⁻⁸ W/cm² are obtained, yielding images of excellent clarity and contrast.
