12 Determination of the Optical Parameters …
Input parameters:
n j (λ) + iχ j (λ) is refractive index of the jth layer,
d j is thickness of the jth layer,
λ is the wavelength.
Output parameters:
I = I (υ x , t, n j , χ j , d j ) are the dependences of the intensity of the laser radiation
on the refractive index and absorption coefficient
for the system of blood vessels in the upper dermis
Experimental measurement:
I = I (υ x , t, n j , χ j , d j ) is reflected signal on simulated biological structures.
Calculate:
1. υ x (t) is rate of blood flow in a capillary at the time instant t,
2. I = I (n j , χ j , d j ) are the spectral characteristics for simulated biological structures.
