Reply to Comment on Interferometric phase-only optical encryption system that uses a reference wave
Dong-Hoan Seo, Soo–Joong Kim
Abstract
We appreciate the Comment by Glückstad et al. [Opt. Lett. 28, 1075 (2003)] in the sense that it allows us to clarify an inherent possibility of counterfeiting phase-only encrypted information and some important points in our original Letter [Opt. Lett. 28, 304 (2003)]. We also take this opportunity to show the usefulness of the method that we described.
