speckle interferometryA method of extracting detail in celestial objects that is normally lost because of atmospheric turbulence. It involves taking hundreds of short snapshots, with exposure times of 0.001 to 0.1 second, each fast enough to freeze the blurring effect of the atmosphere, and computer-processing the results.
