Remote Deformation Field Measurement Through Different Media Using Fiber Optics

Abstract
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.
