Scientific paper

We have developed and implemented a new technology for removing the effects of atmospheric turbulence from telescope images. This technology, bispectral speckle interferometry, permits imaging of astronomical objects and satellites to the diffraction limit of the collecting telescope. We have successfully applied this technique to speckle images we obtained with a 1.6 meter telescope at the Air Force Maui Optical Station on Mt. Haleakala, Maui. We have extracted diffraction-limited features of several satellites, including the Hubble Space Telescope. This technology should have a positive impact on both astronomical and defense imaging problems.
