Optical Effects of Atmospheric Turbulence,The aim of this Chapter is to provide a . introduction to the optical effects of atmospheric turbulence on astronomical images. A number of more detailed descriptions should be read in conjunction with this Chapter and those by Roddier[13][14], Fried[5], and Roggemann and Welsh[16] are particularly recommended.
