摘要：
Method of industrial testing is proposed, in which the surface energy is evaluated whether it is less of a specified value. Evaluation is accomplished by measuring the contact angle of wetting. Method of measurement is based on the analysis of one-dirnensional intensity distribution of laser radiation in the edge diffraction pattern. To increase the rate of digital processing have been derived explicit expressions that relate intensity with the parameters of the shape of wetting liquid in the vicinity of three-phase line.
