Paper Abstract

The advent of low-loss optical fibers in the early 1970s was a major event in the field of communications. Since then, material and fabrication technologies have progressed rapidly and, non-communications applications for fiber optics have become widespread. For example, optical-fiber components are routinely used in holography and holo-interferometry to realize significant improvements in stability, flexibility and accessibility. This paper reviews the history of the application of individual single- and multimode fiber-optic components to the manipulation of both object and reference beams, and the use of multimode fiber-optic image bundles for object-to-hologram wavefront transmission. The advantages and disadvantages of singlemode versus multimode fiber-optic components will be discussed, and techniques for improving the stability of multimode fiber-optic components will be presented. Tests conducted using singlemode fibers (SMF) as stable illuminators and a singlemode image transmitting (SIT) fiber-optic component for wavefront transmission between the object and the hologram will be described. Other techniques which rely on holographic/fiber optic recordings, such as radial metrology and real time moire interferometry, will also be discussed.
