Abstract

The mathematical process of combining the known characteristic functions of a number of optical systems to obtain the characteristic function of the system created by adjoining these component systems is shown to permit a significant simplification: If the intermediate variables are solved as power series to a given order in the external variables, then it is possible to determine the power series for the resulting characteristic function to at least twice this order. This doubling of order is shown to be a direct result of the extremal property of the rays. By way of illustration, the point characteristic of a refracting plane is determined explicitly as a power series accurate to within terms of degree 16.

  12. If a characteristic function is specified as a power series to order N in its arguments, then the equations for the initial and final behavior of the rays are known to order N-1 (since the configuration of the rays is determined by differentiating this function). Consequently, the characteristic function is said to be determined to order N-1. For example, the expansion of V(y, y″) given in Eq. (3.11) is correct to order 14 or, using the above convention, determined to "order" 13. To avoid confusion, this convention will always be distinguished with the use of quotation marks.
