Présentation de l'éditeur
Accurate, comprehensive and precise, this revision provides students with the most up-to-date coverage of optics. Responsive to students' needs, the focus of the revision was to fine tune the pedagogy, modernize the discourse, and update the content. The third edition continues the gradually modernizing treatment of the previous edition by imparting an appreciation of the central role of atomic scattering, providing an understanding of the insightful perspective offered by the Fourier Theory, and by, from the outset, explicating the underlying quantum mechanical nature of light. Additionally, the third edition addresses all of today's significant technological advances. As always, Hecht provides a good balance of theory and instrumentation, while also providing readers with classical background. The writing style is lively and colorful, with historical anecdotes and citations, and at the request of previous edition users, Hecht has included about 125 new problems, designed primarily to develop students' analytic skills.

It prepares you remarkably well for any direction in optics you then want to set off in. The explanations are mostly crystal-clear, crafted with great care. Lots of words and diagrams, not too much math, but enough math to facilitate useful calculations.
An excellent under-graduate text, to my mind, the best available today.
I believe most physics students have learnt optics in some way. At a first sight, it seems like the book is talking about the same thing on geometrical and physical optics. It turns out that optics has more depth than I thought. For example, how light interact with the atoms in a material and how it affects light propagation, a deeper look of the Huygens principle, how atoms in an object emit light and the corresponding issue of spatial and temporal coherence. These topics are typically shoved under the carpet in general physics courses. The author has clearly thought out these issues, and I really enjoy his explanations throughout the book. The book is wrapped up by an introduction of Fourier optics, which links previous chapters together and opens up many possible applications of optics.
Overall, I like this book. Quite often, I find that the book feels like a big block of words. I believe the underlying reason is that many topics are indeed quite complex, but instead of writing pages of formula, a more qualitative description is adopted for undergraduates. As a result, the book feels a bit too wordy. From the students' point of view, they might find it hard to revise their tests and exams using this book. The style of the book is like pages of text interlaced with a couple formula, and there are no examples. But still, Hecht is certainly a good read if you want to understand the physics of light.
On the other hand, Hecht does not give many example problems, and sometimes he entirely breezes over the math behind certain phenomena, and while I appreciate the clarity of his qualitative descriptions, I feel pretty crippled if I cannot mathematically characterize the optical systems I'm studying. On the other hand, sometimes he goes overboard with some pretty confusing math, like the math behind the Cornu spiral. This graph is used to help figure out the spacing of Fresnel diffraction lines, but Hecht layers on some very confusing electromagnetic wave theory on top of the basic function, and I had a hard time trying to understand what he was describing.
This is still a great beginning's text, but it should be bulked up a bit with more solved problems and mathematical examples, and some things like the Cornu Spiral should be wholly reworked.
