Previously, no simple continuous expression was available for estimating the refractive index of brine at subzero temperatures. I show that extrapolation of the empirical formula for the refractive index of seawater by Quan and Fry [Appl. Opt.34, 3477 (1995)APOPAI0003-693510.1364/AO.34.003477] ...
However, as the value of the piezo-optic coefficient is tiny27, the high-order variation in the refractive index caused by optical nonlinearity can be ignored in equation (1). It should be pointed out that the influence of cavitation on the Lorentz formula is strong. When cavitation occurs,...
Instrument units were converted to mean residue molar ellipticity according to the formula: θ = millidegree/molar concentration/number of amino acids. The percentage of secondary structure was calculated using the following formula: % helicity = 100 ×θ222(observed)/θ222(max), where θ222(max...
Snell's law relates the incidence and refraction angles to the refraction indices of the media involved. Learn more about the Law of Refraction, its formula, definition and more.
The variation—perturbation method is employed for the estimation of the frequency‐dependent polarizability and the refractive index of the hydrogen molecule. Use of a one‐term expression for each component of the perturbation function leads to a simple formula for the frequency dependence. Application...
Fitting refractive-index data with the Sellmeier dispersion formula The fitting of measured optical index data to the Sellmeier dispersion formula, using the variable projection algorithm, is described. Examples of fits obt... Tatian,Berge - 《Applied Optics》 被引量: 225发表: 1984年 Measurement ...
Its formula is silica-H-L-H-L-H-air, where H and L denote Ta(2)O(5) and SiO(2)lambda/4 layers, respectively, with lambda = 514.5 nm. Measurements indicate that the refractive index of Ta(2)O(5) is 5 x 10(-3) greater when the layer is close to air than when the layer ...
,T(h) is the temperature profile in K andP(h) is the pressure profile in hPa. The structure function of the temperature fluctuation\({C}_{T}^{2}\)is evaluated by the AXP model37. The refractive index structure constant\({C}_{N}^{2}\)is then estimated by the Gladstone formula...
