Term Categories: Glossary

The method used to show information. This may include A-scans, B-scans, C-scans, or D-scans.

The reproducibility of measurement; the closeness of each of a set of similar measurements to the arithmetic mean of that set.

The property of being porous.

A term describing a test method in which the ultrasonic energy is emitted by one transducer and received by another on the same or opposite surface.

The properties of a material that are relatively insensitive to structure and can be measured without the application of force. Examples are density, melting temperature, damping capacity, thermal conductivity, thermal expansion, magnetic properties, and electrical properties.

The velocity of a single frequency continuous wave.

A measure of the offset between two periodic signals of the same frequency. Measured in degrees or radians.

A mosaic of transducer elements in which the timing of the elements’ excitation can be individually controlled to produce certain desired effects, such as steering the beam axis or focusing the beam.

The difference in phase between two sinusoidal varying quantities.

The property which enables a three-dimensional material to store electrical current; i.e. its capacitivity.
