heal.abstract	The determination of the tissue optical parameters and the study of light propagation in multicomponent tissues is an important tool for real time laser treatment dosimetry and non-invasive laser diagnostics. The purpose of this work was the evaluation of a small portable spectrophotometry system, for non-invasive laser dosimetry, as compared to a more sophisticated, tabletop, spectroscopic system. The small portable system consists of an optical spectrum analyser, an oscilloscope and appropriate fibers, while the complete laser spectroscopy system consists of a spectrograph, an integrating sphere and a photodiode array as a detector element. The determination of the optical properties of soft and hard biological tissues - in vitro - was performed with both systems. Spectral information obtained, the appropriate mathematical modeling and the comparative results are discussed.	en
