The measurement of the ion velocity distribution in full three-dimensional velocity space is studied with a planar retarding-grid rotating analyzer immersed in plasma. In spite of the plane geometry of the analyzer, the current-voltage measurement in different directions can provide useful information for the three-dimensional measurement with the aid of numerical techniques of computerized tomography. The practical usefulness of this method as a diagnostic tool is shown experimentally for a weakly ionized collisionless argon plasma into which a low-energy ion beam is injected uniformly. Discussions are made with emphasis on the optimization of measurement by compromising the contradiction between the spatial resolution and the statistical accuracy.
