Principles of Biophotonics, Volume 3

Field propagation in linear, homogeneous, dispersionless, isotropic media
Gabriel Popescu


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 Vol. 1.

Key Features:

  • A homogeneous, self-consistent reference that covers this interdisciplinary field.
  • Books are intended to be used as reference for a two-semester course on Principles of Biophotonics.
  • Aim is not only to provide a "how to" user guide for these techniques, but to clearly present the optics foundation that allows them to function.

About Editors

Gabriel Popescu is the William L. Everitt Distinguished Professor of Electrical and Computer Engineering at the University of Illinois Urbana–Champaign. He received his PhD in optics in 2002 from CREOL, The College of Optics and Photonics, University of Central Florida. He continued his training with the late Michael Feld at MIT, working as a postdoctoral associate. He joined Illinois in August 2007, where he directs the Quantitative Light Imaging Laboratory (QLI Lab) at the Beckman Institute for Advanced Science and Technology. Aside from Principles of Biophotonics, he has authored another book on quantitative phase imaging, edited a title on nanobiophotonics, authored 200 journal publications, 240 conference presentations, 32 patents and has given 235 lecture/plenary/invited talks. He founded Phi Optics Inc, a start-up company that commercializes quantitative phase imaging technology, and he is a Fellow of OSA, SPIE, and AIMBE, as well as being a Senior member of IEEE. Professor Popescu also won the SPIE Dennis Gabor Award in Diffractive Optics in 2022.
