Book excerpt: Prof. Boudoux's book covers a comprehensive range of topics in biomedical optics and biophotonics. The organization of the material is well thought out, starting off with a toolbox of essential concepts that are general and yet detailed enough for a broad range of student backgrounds. The heart of the book covers the essential topics of tissue optics, as well as optical imaging system design concepts. With a well-balanced combination of engineering and physics, this text is an asset for students, and will be a valued long-term reference.
