Reversible mirror for real-time holographic interferometry
Abstract
The problem of poor fringe contrast in holography has been partially solved by optically flattening both sides of a black disk, and aluminizing one side to give high reflectivity. The disk may be maneuvered so that the low-reflectivity surface reflects the reference beam when the hologram is recorded, and the high-reflectivity surface is used when the hologram is reconstructed. Photographs are presented to illustrate the comparison.
