advanced interferometry

Advanced interferometry is a precise measurement technique that compares the wave patterns of light or radio signals to detect extremely tiny changes in distance or position. By splitting a signal into multiple paths, bouncing them off different objects or locations, and then recombining them, scientists can observe how the waves interfere. This interference reveals minuscule differences, enabling highly accurate measurements. Applications include detecting gravitational waves from space, mapping Earth's surface with incredible detail, and improving the precision of telescopes. It leverages the wave nature of signals to push the limits of measurement sensitivity and resolution.
