Abstract
This paper describes some recent advances in the use of electrostatic transducers for performing ultrasonic measurements in both air and water. It will be shown that through-transmission imaging can be performed in metals, polymers and fibre-reinforced composites. Also possible are various forms of imaging in air, including tomographic reconstruction of flow and temperature fields in gases.
