Heterodyne quadrature interferometer for simultaneous measurements of plasma density along several chords.
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.
