Paper Abstract

In the paper an application ofthe generalized rn-line spectroscopy to test of biological samples is presented. A generalized rn-line spectroscopy enables an evaluation ofthe parameters (the refractive index, n and the thickness, d) of sub-guiding films deposited on a planar waveguide. Examined layer ofbiological liquid between planar waveguide and prism changes the angular and intensity distribution of rn-line structure of outgoing beam. Some initial measurements reveal an effect of the presence of the films on the coupling angles of the structures. The method is noninvasive and for measurements merely small amount of substance as a drop of tiers or sweat can be used.
