title: Real time moire interferometry using a Fabry-Perot cavity with a phase conjugate mirror.
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 BaTiO(3) crystal as a PCM are analyzed.
