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 new book by an industry expert, Ronian Siew (with a Foreword by Mark Nicholson, CEO of Zemax LLC). 

Ronian Siew believes that a chance encounter with a flashlight at the age of three had planted a subconscious aspiration in him to become an optical engineer. At the age of eleven, using scrap lenses salvaged from junk, he began constructing simple optical systems that, arguably, worked "just as I expected, more or less". Today, his professional optical designs have included a variety of imaging and detection systems that, to the best of his knowledge, actually works as he had expected. Ronian holds a Master of Science in Optics and a degree in physics from the University of Rochester, and he is the author of a number of peer-refereed scientific articles. He is also the author of that "bright red book" on modern optics and imaging (whose design examples are now available as sample lens files in the latest release of Zemax OpticStudio).
