Image quality and active optics for the Gran Telescopio Canarias
The conceptual design of the Gran Telescopio Canarias (GTC) has been completed. One of the challenges facing the GTC Project is to obtain excellent image...
A multi-mission image search tool has been created through a collaboration between Google and NASA Ames Research Center, using Google Earth as a virtual...
Image sharpening algorithm at low light level. On-line reduction.
The authors study the behaviour of a family of algorithms with different weight functions in an approach to algorithms working in real time. The behaviour of...
Image sharpening observations of active galactic nuclei
It is shown that recentering, selecting, and adding up sharp short-exposure images obtained with a photon-counting detector working in time-resolved mode can...
Images at the Highest Angular Resolution with GRAVITY: The Case of η Carinae
The main goal of an interferometer is to probe the physics of astronomical objects at the highest possible angular resolution. The most intuitive way of doing...
