Coaxial Fiber Delivery of Object and Reference Beams for Pulsed Ruby Laser Holography

Abstract

The fiber delivery of the reference and/or the object beam may be useful or even required for a number of holographic applications. This is particularly true for endoholography, or holographic recording of internal cavities1,2. The design and utilization of such fiber systems can become rather challenging if single-mode fibers and pulsed lasers are used.
