Abstract

By using an isotropic fiber-optic probe together with an accurate mechanical positioning system, the fluence rate distributions (2-D, 3-D) were measured in normal and squama- carcinomatous human lung tissues in vitro for incident irradiance of 22 mW/cm^{2$ and wavelength 413.1 nm of a Kr(superscript +} laser for beam diameters of 1 mm and 4.5 mm respectively. Monte Carlo simulations of light distribution in the tissue were performed and compared with the experimental results. The optical properties of human lung tissues at 413.1 nm were estimated.
