A Displacement Measuring Interferometer Based on a Frequency-Locked Laser Diode with High Modulation Frequency
Laser interferometers can achieve a nanometer-order uncertainty of measurements when their frequencies are locked to the reference frequencies of the atom or molecule transitions. There are three types of displacement-measuring interferometers: homodyne, heterodyne, and frequency modulation (FM) int...
