WebbThe small-deformation theory (or, equivalently, the small-strain or infinitesimal theory) is customarily obtained by assuming that the displacements u are small, and expanding u in a power series with respect to a small parameter. 12 As a consequence of this approximation, ( 3.7 ), ( 3.27 ), ( 3.36 ), ( 3.54 ), and ( 3.55) become, to leading ... Webb22 sep. 2009 · In this chapter we assume that the angles between the rays and the axis are so small that the images formed are essentially perfect. The resulting approximate theory of lenses is called the paraxial approximation, or Gaussian optics. We use in this chapter an abstract method based on eikonal function theory.

In geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens). A paraxial ray is a ray which makes a small angle (θ) to the optical axis of the system, and lies close to the axis throughout the system. Generally, this allow…
