This volume describes light propagation in free space, including diffraction, geometrical optics, Gaussian beams and propagation of field correlations. It is a textbook for experimentalists who are active at the interface between biology, medicine, and optics.
This volume aims to familiarize the reader with basic concepts of light propagation in the simplest class of media: linear, homogenous, dispersionless, and isotropic. After a review of Maxwell’s equations in both integral and differential forms, the book describes the field propagation from elementary sources (dipoles) and in free space, in 1D, 2D, and 3D. Next, the material covers diffraction of light by a 2D screen, with various levels of approximations, emphasizing the wavevector space calculations. The ABCD matrix propagation is introduced as an efficient tool for both ray optics and Gaussian beam propagation. The volume ends with a chapter on propagation of field correlations, generalizing the coherence concepts introduced in Volume 1.
