For a Gaussian shaped spectrum S(k) with standard deviation [[sigma].sub.k] and center wavenumber
[k.sub.c] the OCT axial PSF is
Figures 7(a) and 7(b) show the variations of [F.sub.x,2]/[rho]ghA and [F.sub.z,2]/[rho]ghA versus the dimensionless wavenumber
The spectrum of 2-pyrrolidone treated with [C.sub.70] shows only a very slight broadening of the carbonyl absorption on the low wavenumber
side at 5 [micro]l of 2pyrrolidone per mL of toluene saturated with [C.sub.70].
In Figures 4a-b, absorbance, wavenumber
and representative time are coordinates.
Variation of group velocity and effective index with the reduced wavenumber
are plotted for characterizing the slow-light.
The increases in yellowness ([b.sup.*]-value) of gelatin gel from skin pretreated for a longer time were in agreement with the shift of Amide A and B to the lower wavenumber
A local wavenumber
of the event is calculated using
Where R([omega]) is the reflectance at a particular wavenumber
. The refractive index N is the most widely physical quantity used in optical design.
There is no critical frequency, beyond which there are no solutions, as in the Rayleigh-Love model, so that a wavenumber
k can be obtained for any frequency.
The C-H peak shifts to a higher wavenumber
for Sample F3, whereas this peak shifts to a lower wavenumber
for Sample F4.
So we perform Fourier analysis in plane waves and assume that all perturbations are of the form [e.sup.i(k,r-[omega]t)] where k = [k.sub.x][??] + [k.sub.z][??] is the wavenumber
and [omega] to is the frequency.
