Fringe number

First the signal was smoothed through a Savitzky-Golay algorithm, whose parameters were optimized considering the mean fringe number for a fixed temperature variation. 

In addition to the deflection Yh primary observable quantities are the fringe number, /, and the total number of fringes, m. The total path difference corresponding to the fringe numbered / is given for ideal diffusion by the path difference function (6). 

It is noted that an independent value for D is obtained from every fringe numbered / whose deflection Yj is measured. For nonideal diffusion, Ct actually will show a drift with fringe number, and the value Ct corresponding approximately to the middle of the diffusing boundary is obtained by an extrapolation procedure (27). Akeley and Gosting (27) developed the deviation function defined by...

At equilibrium, the concentration at the air-solvent meniscus remains finite, but can be found without too much difficulty by mathematical manipulation of the fringe data. A typical plot of In J vs. where J is the absolute concentration (in fringe numbers) and = (r — a )/(b — a ) [r being the radial displacement from the center of the rotor, and a and b the correspond-...
