Speckle Interferometry

Speckle interferometry is a high-resolution imaging technique used to observe celestial objects, like stars or planets, through Earth's atmosphere. When light from these objects passes through the turbulent air, it creates a pattern of tiny, rapidly changing spots called "speckles." By capturing many short-exposure images and analyzing the speckle patterns mathematically, astronomers can reconstruct a clear image, effectively bypassing the blurring caused by atmospheric turbulence. This method allows for detailed observations of objects that would otherwise appear blurry, enabling scientists to study their features and understand their properties with greater precision.
