Abstract

Detecting weak acoustic fields using optical-fiber system for purposes of nondestructive diagnostics. M.N. BEZRUK, R.V. ROMASHKO, Yu.N. KULCHIN (Institute for Automation and Control Processes, FEB RAS, Vladivostok).

In this paper, the possibility of using fiber-optical system based on a multi-channel adaptive holographic interferometer in the problem of non-destructive diagnostics is demonstrated. The detection and reconstruction of a weak acoustic field formed inside the plate from a structural material having a structure defect has been performed. Based on the results of tomographic reconstruction of the acoustic field, the effect of structure defect on the superposition of the acoustic field inside plate is shown.
