انموذج رياضي لحساب قيم عتبة القدرة الليزريةالداخلة الى العين

Mathematical relations has been derived to make a model for calculating the values of direct retinal irradiations by a laser energy at narrow and far Field of view (FOV), also the mathematical relations for indirect reflections of a laser irradiation has been calculated. The effect of laser power on the human eye for four laser types (two Ion Argon, Ruby, Nd: YAG) calculated at range of two kilometers .
