Abstract

The resolution of conventional astrophotography is limited to 1 arcsec by the turbulent atmosphere of the earth. Triple correlation analysis"2(speckle masking) of many astronomical speckle interferograms (short-exposure photographs; exposure time 0.05 sec) yields diffraction-limited images with, for example, 0.02 arcsec resolution for a 5-m telescope.
