Applications of time-averaged digital holographic interferometry

This work reports on recent results in the area of the time-averaged digital holographic interferometry. Two techniques are described, one that re-moves the zero-order reconstruction term thus allowing recording of large objects, and the other by which the hidden stationary deformations can be detected. Quantifying hidden deformations is important because its evaluation allows direct measurement of a stationary bias strain in the dynamic analysis of the vibration object. These two techniques are ex-plained mathematically and illustrated by the experimental results.
