Description

Laser-based methods of nondestructive testing using holographic techniques have been used extensively by the NDE community for many years. Techniques such as holographic interferometry [1] and frequency-translated holography [2] have provided measurements of surface displacement, vibration frequency analysis, and surface wave characterization for a variety of materials. The importance of such measurements, and advantages holography has over other NDE techniques include its ability to provide full field, instantaneous, and non-contact measurements of a variety of material parameters with sub-micron spatial resolution capabilities.
