title: Heterodyne quadrature interferometer for simultaneous measurements of plasma density along several chords.
abstract: An interferometer has been developed with which it is possible to make simultaneous measurements of plasma density along several chords. A single Bragg cell and laser are used, and the phase detection is in quadrature in order to obtain unambiguous and uniformly sensitive readings.
