Abstract

An intensified video camera with digital video readout has been implemented for use with the Steward Observatory speckle camera. Video subtraction algorithms implemented in a Grinnell digital television system can provide either photoelectron response records for faint objects or background subtracted analogue records for bright objects. The required speckle image power spectra are computed indirectly from the autocorrelation functions accumulated from the event address lists produced for faint objects or directly by Fast Fourier Transform techniques from the analogue data for bright objects. Methods for producing properly deconvolved, noise bias corrected power spectra have been developed. The system has been applied successfully to recover high resolution images for objects ranging from magnitude 0 Capella to the magnitude 16 QSO PG1115+080A.
