Optical heterodyne detection is a technique used in optical communications and spectroscopy to measure the frequency and phase of light waves by mixing them with a reference beam of slightly different frequency. This process generates a beat frequency signal that is easier to measure and analyze, enabling precise measurements of optical properties and high-resolution imaging.
