Rayleigh refractometer
Webcommon method is interferometry including Rayleigh refractometer, Mach-Zehnder, Michelson and Fabry-Perot interferometer and more [2]. By means of them, the RI of the medium can be measured by detection the critical angle of total reflection, backscatter or interference patterns. However, all of these conventional methods have many … WebWhat is a Refractometer? Refractometers are specialist environmental test and measurement devices used to measure the angle of refraction - the extent to which light changes direction when passing through a translucent substance such as an aqueous solution. Refractometry is a widely used technology because this angle can be used to …
