METHOD FOR DETERMINING COMPONENTS OF VECTOR OF MOVING POINTS OF OBJECT SURFACE

摘要

The invention relates to the field strength of test specimens and elements of field constructions in various types of loading. The aim - increase in the accuracy of determining the normal component of the movement vector. Attached to the surface of the object by means of an intermediate optical photographic plate medium after recording a double-exposure hologram on the surface of the photographic plate is applied diffusely reflecting layer is set in front of the photographic plate in the course of radiation additional photographic plate and recorded thereon hologram before and after re-loading the object is removed coating the first surface photographic plates, photographic plate is reduced with more double-exposure hologram recorded interferogram and calculating COMPONENT ent movements carried out on the basis of matching fringe patterns obtained with the two photographic plates. The proposed method improves the accuracy of determining the movement of the component in view of accounting photoplates deflection. 10
