  • Abstract
    We describe a new technique to enhance the image in the scanning acoustic microscope in the reflection mode. We use a 20 ns pulse modulated r.f. signal and a sampling oscilloscope to separate the incident signal from the reflected signal. The resulting image shows up details that are of the order of one micrometre with a good signal/noise ratio. We can further improve this resolution by phase measurements.
