25 November 1985 Differential Speckle Imaging With The Cophased Multiple Mirror Telescope

A new technique known as Differential Speckle Interferometry has been applied to data obtained using the fully-phased six-mirror aperture of the Multiple Mirror Telescope. By observing stellar objects at two distinct wavebands simultaneously, differences in the object resulting from the different wavelengths can be derived. Observations were made of the supergiant star Alpha Orionis in order to investigate the Hydrogen-alpha emission from the surrounding envelope. The data reduction process consists of a frame-by-frame weighted deconvolution procedure. This process involves an inherent Wiener-type filtering which must be removed in order to preserve high spatial frequency information. Results for Alpha Orionis and for the unresolved source Gamma Orionis are presented.
