Paper Abstract

It is shown, that the singlefiber doublemode interferometer implanted into structure of a tested concrete unit allows to measure the unit structural deflection, absolute elongation and residual deformations in real time with accuracy not worse, than 0.05 μm. it is also shown, that the developed interferometric method allows to indicate a point of time of unit's crack initiation and to estimate the crack opening displacement.
