Effect Of Structure

Продемонстрирована возможность применения волоконно-оптической системы на основе многоканального адаптивного голографического интерферометра для задач неразрушающей диагностики. С помощью системы выполнены детектирование и реконструкция слабого акустического поля, сформированного внутри плиты из конструкционного материала, имеющей неоднородную структуру. На основе результатов томографической реконструкции акустического поля показано влияние неоднородности на суперпозицию акустического поля. 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.
