1. A technique that uses the interference of waves (such as light or radio waves) to measure distances, detect objects, or analyze properties of materials with high precision.
Usage: technical; used in physics, astronomy, and engineering

Examples

• Astronomers use interferometry to combine signals from multiple telescopes and achieve greater resolution.
• Laser interferometry can measure distances accurate to a fraction of a wavelength.
• The research team employed interferometry to detect gravitational waves.
• Optical interferometry is essential in precision manufacturing and quality control.
• Radio interferometry allows scientists to map distant galaxies with remarkable detail.
