The advantage of the rapid development of fiber optics for communication purposes is that now holographic investigations can be made much more flexible if fibers are used. The use of optical fibers in connection with cw lasers has already found interferometric applications within metrology. The possibility of using a pulsed laser with fibers will open important new applications for hologram interferometry within science, industry, and medicine. A fiber coupling technique for pulsed lasers is described, as well as suitable equipment for pulsed or cw laser holographic investigations. Possible applications also are discussed.
