A simple method to measure critical angles for high-sensitivity differential refractometry
A simple method to measure critical angles for high-sensitivity differential refractometry is a scholarly work, published in 2012 in ''Optics Express''. The main subjects of the publication include measure, optics, reflective programming, ptychography, physics, Total internal reflection, refractometry, paper studies, surface roughness, Fresnel equations, Electrowetting, refractometer, materials science, phase, sensitivity, and refractive index. A total internal reflection-based differencial refractometer, capable of measuring the real and imaginary parts of the complex refractive index in real time, is presented.
