The determination of the optical constants of plant leaves using polarized emission

There have been given the results of the investigating the reflection coefficients of some plants' leaves with very smooth surfaces in the polarized light for those wave lengths for which the inner composition in the reflected emission does not practically exist. The optical constants for the mentioned objects of investigation have been defined, also Fresnel formulas as well as the method of the determination of the optical constants based on the measuring the reflection coefficients of the polarized emission for the definite fixed angles of incidence.
