Guiding and Acquisition with NIRCAM

open access: yes, 2000
By investigating the centroiding position errors as a function of guide star location within a pixel, observing wavelength, and total counts from the guide star, we are able to derive the probabilities of finding bright enough guide stars as a function ...

A laser guide star wavefront sensor bench demonstrator for TMT

open access: yes, 2008
Sodium laser guide stars (LGSs) allow, in theory, Adaptive Optics (AO) systems to reach a full sky coverage, but they have their own limitations. The artificial star is elongated due to the sodium layer thickness, and the temporal and spatial variability
