Abstract
A Mach-Zehnder optical heterodyne interferometer with a radio-frequency phase reference is described. The system, intended for use in the study of turbulent gases and plasmas, has a high phase data rate (3kHz) and can monitor unlimited relative phase excursions. Possible extensions to higher data rates and to dual wavelength operation are discussed.
