Wavefront sensors in Adaptive Optics
(University of Canterbury. Electrical and Computer Engineering, 2008)
Atmospheric turbulence limits the resolving power of astronomical telescopes by distorting the paths of light between distant objects of interest and the imaging camera at the telescope. After many light-years of travel, ...
Wave-front sensing for adaptive optics in astronomy
(University of Canterbury. Electrical and Computer Engineering, 2002)
Optical images of astronomical objects viewed through ground-based telescopes are blurred by the atmosphere. The atmosphere is turbulent and as a consequence the density of air is not evenly distributed. This results ...
