Abstract
We 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.
