Some Theoretical and Experimental Facts Concerning Laser Interaction With Materials of Biological Origin
Year: 2015
Type: article
Abstract: This paper deals with characterization of materials, by the use of objective descriptions of material’s 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.
