Convolutional neural network optimisation to enhance ESPI fringe visibility
Journal of the European Optical Society-Rapid Publications, 2023 The use of convolutional neuronal networks (CNN) for the treatment of interferometric fringes has been introduced in recent years. In this paper, we optimize and build a CNN model, based U-NET architecture, to maximize its performance processing ...

Automated Speckle Interferometry of Known Binaries [PDF]
arXiv, 2023 Astronomers have been measuring the separations and position angles between the two components of binary stars since William Herschel began his observations in 1781. In 1970, Anton Labeyrie pioneered a method, speckle interferometry, that overcomes the usual resolution limits induced by atmospheric turbulence by taking hundreds or thousands of short ...
