This series of tests demonstrates the feasibility of recording deformation holograms of reflecting subjects that are not mounted on an optical bench and vibration-isolated and that, in fact, can even be submerged in a transparent liquid. This represents an important extension of research into the use of fiber optics in holography. Various considerations for the ultimate development of a practical fiber optic device for making in-situ or "production environment" deformation field measurements by continuous wave holographic interferometry are also discussed.
