'Bigio and Fantini provide a long-needed introduction to the field of biomedical optics and biophotonics, adding spice to the presentation of the basics with historical and etymological gems. The conversational tone of the book is very welcome, and allows room for the clear explanation of subtleties not always clarified in other discussions. The book is a wonderful introduction to the field. It balances rigor with readability. Bravo!' Steven L. Jacques, Oregon Health Sciences University
