Monochromatic Third-Order Aberrations

In Chapter 2 we presented the paraxial or Gaussian theory, which describes the propagation of light across an optical system S , but only for rays that are close to the optical axis a and that subtend small angles with it. We showed that, under these conditions, the correspondence between an assigned pair of object and image planes π and π ′ is given by the linear relations These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
