Skośne prześwietlanie w metodzie warstwy elastooptycznej
Paper presents mathematical model permitting analysis of the effect of different type of polariscopes in photo-stress method. This model enable pointing out errors in oblique incidence method. New technique of photo-stress measurement to separate strains is also described. Its principal advantages are that only standard photo-stress equipment is needed and results obtained by this method are more reliable.
