Descripción
Exponential filtering, together with an improved version of the
iterative Fourier-transform algorithm, is applied to image
reconstruction from one-dimensional infrared stellar speckle
interferometry data. The only problem was an expected noisy appearance
of the results when noisy data were simulated. Finally, the method was
applied to observational specklegrams of the infrared source IRC +
10216, in two standard photometric bands: K and M (2.2 and 5 microns,
respectively). The reconstruction in K of a north-south scan clearly
shows three components inside a circumstellar shell. On the other hand,
in the M band only a wing on the north side of the main component is
resolvable.
