Capacitor Technique for Measuring the Velocity of a Plane Conducting Surface
Melvin H. Rice · Review of Scientific Instruments · 1961
A capacitor method for measuring the velocity of a plane, conducting surface is described. An advantage of the method is that the signal voltage developed is essentially proportional to the velocity of the surface instead of to the displacement. Consequently, the method is useful in measuring a surface velocity which persists only over a small displacement interval.
