Abstract

The proposed method is based on the law of reflection and can be used for large reflective continuous surfaces, which behave approximately as a deformable mirror of a general type. For successful application of the ray method for deformation measurement is crucial the reflectivity of the surface. If the measured surface is optically rough, then the light is diffusely scattered in different directions relating to the microstructure of the surface, and the described method cannot be used. To limit the influence of the surface roughness the plastic reflective foil can be affixed on the test surface. The research was focused on several theoretical and experimental aspects of evaluation of the deformations with the ray method, especially on problems of measuring extended objects in engineering practice and automatic process for evaluation of deformations.
