The Use of Fabry-Perot Filters for Spectral Scanning
Published online by Cambridge University Press: 25 April 2016
Extract
In designing a stellar spectrograph, it is pointless to exceed the resolving power necessary to obtain all the information from the spectrum of a star. This is limited mainly by atomic thermal motions, giving rise to the Doppler broadening of spectral lines, by turbulence and rotation of the stellar atmospheres in which the lines are formed, and by collisional broadening.
