An image reconstruction for Capella with the Steward Observatoty.
Abstract
Since their invention in 1970, speckle interferometric techniques have evolved from simple optical processing of photographic images to high-speed digital processing of quantum-limited video data. Basic speckle interferometric techniques are discussed, taking into account the implementation of two distinct data-recording/data-processing modes. A description of image reconstruction techniques is also provided. Two methods for image phase retrieval have been implemented, including a phase unwrapping method developed by Cocke (1980) and the phase accumulation method of Knox and Thompson (1974). On February 3, 1981, analogue mode speckle interferograms for Capella and the unresolved star Gamma Ori were obtained with both the phase-unwrapping and the Knox-Thompson method.
