15. A FORTRAN routine to estimate a function of two variables from its autocorrelation

Author

Nieto Vesperinas, Manuel, Fuentes, F. Javier, Navarro, Rafael, Pérez-Ilzarbe, M. J., Nieto Vesperinas, Manuel, Fuentes, F. Javier, Navarro, Rafael, and Pérez-Ilzarbe, M. J.

Abstract

We describe a simulated annealing routine that yields an estimate of a function of two variables from its autocorrelation. This is equivalent to retrieving the phase from the modulus in Fourier space. © 1993.

21. One-dimensional image reconstruction by exponential filtering in infrared stellar speckle interferometry: application to IRC +10216

Author

Navarro, Rafael, Benítez, Domingo, Fuentes, F. Javier, Navarro, Rafael, Benítez, Domingo, and Fuentes, F. Javier

Abstract

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 performance of the method is checked first by computer simulations with both noiseless and noisy data and then with a realistic simulation of one-dimensional infrared stellar speckle interferometry. We have seen no problems with convergence. The only problem that we found 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 m, 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.

32. Simulated annealing image reconstruction in photon-limited stellar speckle interferometry

Abstract

Contiene fórmulas y 6 ilustraciones., The Simmulated Annealing algorithm for phase retrieval has been applied in image reconstruction from low-light level Stellar Speckle Interferometry (SSI) data. A realistic computer simulation of photon-limited SSI has been performed, successfully obtaining a reconstructed image. The algorithm has been shown to be robust, and able to give good reconstructions of complex astronomical objects with high dynamic range, even in the presence of large amounts of photon noise. Its performance seems so far limited by its considerable computing time requirements., Authors would like to thank the Comisión Interministerial de Ciencia y Tecnología for the financial support of this work (Projects PA-0239 and PB-0278)
