Pitch & Catch

Pitch & Catch

In TOFD, the pitch & catch probe configuration is used.

  1. One probe is emitting the ultrasound wave
  2. Another probe is receiving the signals

The probes used in TOFD have a large bandwidth and high damping. They are usually the same type of probe for emitting and receiving.
