Thermography vs holographic techniques for nondestructive testing of composites: similarities, differences and potential cross-fertilization

摘要

Thermography and holography are full-field non-contact techniques which are used in nondestructive testing (NDT) applications. Thermography is a step forward to holography for damage detection because it is easier to interpret. We discuss their common aspects and what distinguish them. Also the complementarity of both is addressed and an innovative combination of both is proposed. At last we show how processing developed for thermography can benefit to holography, specifically in the domain of composite materials
