This paper is devoted to a practical verification of applying the Phong model, conducted based on available survey data obtained in field conditions. This model has already been described in previous articles, in which authors, using surveys performed in laboratory conditions, showed how to change the shape of the Phong model function depending on the material on which the laser beam falls. In subsequent publications, the focus was on the relationship between the incidence angle and the maximum distance that can be measured by the rangefinder. The measuring data were obtained as a result of scanning the furnace wall in the heat and power station in Pruszków, Poland with the use of reflectorless laser. The presented way of computation has been substantiated on the basis of calculated quantities, incidence angle and empirically defined parameters of the Phong model.
