It’s been some 5 years since I wrote my last “Optics basics” post! The goal of that series of posts was to introduce some of the most fundamental concepts in optics in a non-technical way, in part so I wouldn’t … Continue reading
In all of my discussions of basic principles of optics, I’ve so far neglected to talk about one of the most fundamental and important: refraction! In short, refraction is the bending of a ray of light when it passes from … Continue reading
In my regular discussions of optics and electromagnetic fields in general, I use a lot of pictures with arrows on them. For instance, my post on Faraday’s law has the curious figure, where the red arrows represent the “electric field” … Continue reading
My goal in my “basics” series of posts is not just to introduce the most elementary topics in optical science, but also to give background on some of the more advanced concepts for future reference. Much of my own research, … Continue reading
One of my goals in blogging has been to run a series of posts covering the “basics” of optics, namely those concepts that form the basis of an understanding of the more advanced topics investigated by researchers today. Though I’ve … Continue reading
As I’ve so far been restricting my ‘optics basics’ posts to discussions of fundamental concepts related to optics, it might seem strange at first glance to dedicate a post to a single optical experiment. What will hopefully become clear, however, … Continue reading
In previous posts, I’ve talked at some length about computed tomography (CT) and optical coherence tomography (OCT). Each of these is a technique for determining information about the internal structure of an object, such as the human body, from exterior … Continue reading
