Interferometry is a technique used in astronomy that combines the signals from multiple telescopes to create a single, high-resolution image of an astronomical object. This method takes advantage of the wave nature of light, allowing for improved sensitivity and resolution beyond what individual telescopes can achieve. By measuring the interference patterns created by the overlapping light waves from distant sources, astronomers can glean more detailed information about the structure and composition of celestial bodies.
congrats on reading the definition of interferometry. now let's actually learn it.
