The creation of this 5th edition was guided by three overarching
imperatives: wherever possible, to improve the pedagogy; to
continue to modernize the treatment (e.g., with a bit more on photons,
phasors, and Fourier); and to update the content to keep pace
with technological advances (e.g., the book now discusses atomic
interferometers, and metamaterials). Optics is a fast-evolving
field and this edition strives to provide an up-to-date approach to
the discipline, all the while focusing mainly on pedagogy.
