Abstract

This paper deals with characterization of materials, by the use of objective descriptions of materials optical properties. Here the materials of biological origin were tested. Authors presented their selection of the optical constants for the purpose of material detection and recognition. For plants of interest in medicine and pharmacy (root, fruit and leaves), in their most commonly used state powders, spectral coefficients of reflection in visible spectrum portion were measured. Depending on measurements using correlation methods, chosen groups of parameters were obtained, that could help determine presence of certain species. For characteristic spectra and plant species, certain laser wavelengths were evaluated in the light of being most suitable for distinguishing presence of plants. As second valuable fact, reflection coefficient in bio stimulation determines the level of power (power density, dose, etc) which laser really transfers to the system.
