Abstract

This paper reports on a new form of holographic metrology that enables displacement measurement in both fluid and solid mechanics simultaneously. In such instances, existing holographic methods for displacement measurement would require the application of multiple techniques in a hybrid fashion. Known as object-conjugate reconstruction (OCR), our new approach unifies the disciplines of holographic velocimetry and holographic interferometry. Using complex correlation processing, it provides a sub-wavelength resolution for all three components of displacement and enables automated data extraction at selected points throughout a volume in space.
