Optical interferometry is a technique used in physics, astronomy, and engineering to measure properties of light and make precise measurements of distance, length, or angles. It is based on the principles of interference, where two or more light waves are combined to create an interference pattern that can be analyzed to extract information about the properties of the light waves or the objects that produced them. Optical interferometry is used in a wide range of applications, including astronomical imaging, high-precision measurements in manufacturing and metrology, and medical imaging. It allows researchers to make extremely precise measurements that would not be possible with traditional optical techniques.
