DESCRIPTION

This book, originally published October 18, 2017, has been republished as an eBook on September 8th, 2023.

How would an optical engineer develop a basic model of Google's "Glass" wearable computing device in optical design software? What about an autostereoscopic "glasses-free" 3D display on a mobile phone? Did you know that the brightest position behind a focusing lens is generally not at the focal plane? Or how about the fact that there actually isn't such a thing as the so-called "cosine fourth power law" for the relative illumination of a lens system? These questions (and more) are answered in this book by an industry expert, Ronian Siew. This book provides a brief review of key optics principles, and offers fresh insights and perspectives on the theory and operational principles of a selection of modern optical imaging systems not found in many texts. Practical examples using Zemax's OpticStudio program (with lens prescriptions) are also provided throughout various relevant sections of the book.
