Abstract

In the preceding two chapters, we have described the light path through the atmosphere and into an instrument. On this basis, one can compute the transformation linking the direction from which light entered the atmosphere and the position in which it crosses the focal surface of the instrument, contributing to the formation of the image. Techniques that are used to express this transformation are outlined in Sects. 4.4 and 4.5, and many examples are given in later chapters.
