Optimization of the observations of the high angular resolution techniques (adaptive optics and interferometry)

SPIE Proceedings, 2004
Atmospheric turbulence reduces severely the angular resolution of ground based telescopes and degrades the performances of High Angular Resolution techniques (Interferometry and Adaptive Optics). These observing methods require a better understanding of the behavior of the perturbed wavefronts, more exactly a better knowledge of the atmospheric ...

Ultra-high angular resolution measurements in X-ray astronomy by means of occultation techniques

Acta Astronautica, 1987
Abstract Occultations can provide information concerning angular structure of celestial X-ray sources. For angular scales near or exceeding one arcsec they offer no advantage over other available methods such as focusing optics and coded masks, yet fundamental difficulties preclude using either of those methods to reach milli-arcsec resolution.
