Optical Gyroscopes: Measuring Rotational Changes With Sagnac Effect

Gyroscopes are devices that measure rotational changes. On first mention, most people picture the beautifully rotating classical mechanical gyroscope. Although widely used till the late 1900s, optical gyroscopes have largely replaced as the new industry standard due to having no moving parts, thus being far more reliable and accurate.

In our prior blog post we discussed the properties and major uses of Antireflective Coatings. We also talked about how how anti-reflection is not a property of materials. Rather, it is a consequence of light’s wavelike behavior when passing through a specific geometric setup, and is therefore somewhat independent of which material we are using. Today we … Read more

Anti-Reflective Coatings: Invention Through Current Industry Applications


Everyone knows or heard about UV or anti-reflective coatings on lenses and filters but what are they really and what distinguishes anti-reflective coatings from other types of coatings? We will talk about anti-reflective (AR) coatings in this article and will expand further into the physics of AR coatings in the next article.
