| Title | General Theory of Light Propagation and Imaging Through the Atmosphere |
| Author(s) | McKechnie, T. Stewart |
| Publication | Cham, 1. Imprint: Springer
2. Springer International Publishing, 2022. |
| Description | XXXV, 678 p. 213 illus., 105 illus. in color : online resource |
| Abstract Note | This 2nd edition lays out an updated version of the general theory of light propagation and imaging through Earth???s turbulent atmosphere initially developed in the late ???70s and ???80s, with additional applications in the areas of laser communications and high-energy laser beam propagation. New material includes a chapter providing a comprehensive mathematical tool set for precisely characterizing image formation with the anticipated Extremely Large Telescopes (ELTS), enabling a staggering range of star image shapes and sizes; existing chapters rewritten or modified so as to supplement the mathematics with clearer physical insight through written and graphical means; a history of the development of present-day understanding of light propagation and imaging through the atmosphere as represented by the general theory described. Beginning with the rudimentary, geometrical-optics based understanding of a century ago, it describes advances made in the 1960s, including the development of the ???Kolmogorov theory,??? the deficiencies of which undermined its credibility, but not before it had done enormous damage, such as construction of a generation of underperforming ???light bucket??? telescopes. The general theory requires no a priori turbulence assumptions. Instead, it provides means for calculating the turbulence properties directly from readily-measurable properties of star images |

| Title | General Theory of Light Propagation and Imaging Through the Atmosphere |
| Author(s) | McKechnie, T. Stewart |
| Publication | Cham, Springer International Publishing, 2016. |
| Description | XXIX, 624 p. 190 illus., 13 illus. in color : online resource |
| Abstract Note | This book lays out a new, general theory of light propagation and imaging through Earth???s turbulent atmosphere. Current theory is based on the ??? now widely doubted ??? assumption of Kolmogorov turbulence. The new theory is based on a generalized atmosphere, the turbulence characteristics of which can be established, as needed, from readily measurable properties of point-object, or star, images. The pessimistic resolution predictions of Kolmogorov theory led to lax optical tolerance prescriptions for large ground-based astronomical telescopes which were widely adhered to in the 1970s and 1980s. Around 1990, however, it became clear that much better resolution was actually possible, and Kolmogorov tolerance prescriptions were promptly abandoned. Most large telescopes built before 1990 have had their optics upgraded (e.g., the UKIRT instrument) and now achieve, without adaptive optics (AO), almost an order of magnitude better resolution than before. As well as providing a more comprehensive and precise understanding of imaging through the atmosphere with large telescopes (both with and without AO), the new general theory also finds applications in the areas of laser communications and high-energy laser beam propagation |
