Real-time estimation of the transmission matrix of an atmospheric channel
Cade Peters, Raphael Bellossi, Douglas McDonald +3
Optical wavelengths have received significant attention in free-space channels and are vital for applications in communications, imaging and sensing. Their widespread implementatio…
Online estimation of the transmission matrix of an atmospheric channel
Giacomo Sorelli, Douglas McDonald, Szymon Gladysz
We investigate the reconstruction of the transmission matrix of a time-evolving atmospheric channel with an online recursive optimization routine, using wave-optics simulations. We…
Extended object reconstruction in adaptive-optics imaging: the multiresolution approach
Roberto Baena Gallé, Jorge Núñez, Szymon Gladysz
We propose the application of multiresolution transforms, such as wavelets (WT) and curvelets (CT), to the reconstruction of images of extended objects that have been acquired with…
Review of small-angle coronagraphic techniques in the wake of ground-based second-generation adaptive optics systems
Dimitri Mawet, Laurent Pueyo, Peter Lawson +26
Small-angle coronagraphy is technically and scientifically appealing because it enables the use of smaller telescopes, allows covering wider wavelength ranges, and potentially incr…
Fainter and closer: finding planets by symmetry breaking
Erez N. Ribak, Szymon Gladysz
Imaging of planets is very difficult, due to the glare from their nearby, much brighter suns. Static and slowly-evolving aberrations are the limiting factors, even after applicatio…
Reference-less detection, astrometry, and photometry of faint companions with adaptive optics
Szymon Gladysz, Julian C. Christou
We propose a complete framework for the detection, astrometry, and photometry of faint companions from a sequence of adaptive optics corrected short exposures. The algorithms explo…
