2. We have discussed many of these techniques, but left out acoustical
We have discussed many of these techniques, but left out acoustical. Brief coverage today.

3. Here was the chart for EM techniques. Haven’t covered everything.

4. Let’s look at the acoustical microscope.

5. Why Acoustic Microscopy?

6. Why Acoustic Microscopy?
It is sensitive to “mechanical”
properties of materials.
Can image beneath the surface?
