title: Use of reference beam self-feedback phase modulation in the holographic detection of debonding.
abstract: The use of vibration excitation in the holographic detection of debonding flaws in film-substrate samples is described. The improvements to the technique produced by reference wave phase modulation are discussed and demonstrated.
