Animation of NIST Quantum Probe for Measuring Electric Field Strength (video) National Institute of Standards and Technology (NIST) Share Print E-Mail Loading video... Caption This is an animation of NIST's new method for measuring electric field strength based on the quantum properties of atoms. The technique works for abroad range of frequencies, 1-500 gigahertz, and directly links measurements to the International System of Units. The method could improve the sensitivity, precision and ease of tests and calibrations of antennas, sensors, and other systems.
