Opt. 28, 3893-3896 (1989). doi: 10.1364/AO.28.0038930740-3224http://hdl.handle.net/10919/46957We describe a self-referencing interferometer in which the wavefront and its complex conjugate are generated in a Fabry-Perot cavity having one phase conjugate mirror (PCM). The finite response time of the PCM allows one to display momentarily the moiré between old and new interferograms after a sudden change has affected the input wavefront. Results using an externally pumped BaTiO3 crystal as a PCM are analyzed.en-USIn CopyrightArticle - Refereedhttp://www.opticsinfobase.org/ao/abstract.cfm?URI=ao-28-18-3893https://doi.org/10.1364/AO.28.003893
