Abstract

Speckle imaging techniques are effective post-processing methods to eliminate atmospheric perturbations on the imaging of space objects, in which speckle interferometry and bispectrum methods are usually used to estimate the magnitude and phase spectrum of the objects separately. The spectral ratio technique used in this paper is convenient and efficient to evaluate r0, which is crucial for calibrating the speckle transfer function in the magnitude estimation. It is shown that power spectrum, the second moment of the magnitude spectrum, needs bias removal whereas bispectrum processing does not. Reconstructed images from the observed data of binary stars and Jupiter are presented.
