Fiber-optic measurement grid for registration of the parameters of vibrational processes

We propose a design for a fiber-optic measurement grid for registration of the vibrational parameters of various structural elements. We consider the principle of operation and give an analysis of the output signal of the measurement grid, consisting of quasidistributed fiber-optic sensors of the integrating type. We also describe and experimentally study a model for a grid for registration of the vibrational intensity distribution for the surface of the test object.
