Abstract
Изобретение относится к области неразрушающего контроля и может быть использовано для исследования неоднородностей структуры твердых и жидких сред. Заявленное изобретение обеспечивает расширение возможности применения лазерно-акустического метода контроля твердых и жидких сред за счет исключения необходимости обеспечения плоской поверхности исследуемого материала, повышение точности и надежности контроля за счет снижения влияния качества акустических контактов и собственных колебаний компонентов устройства на регистрируемые акустические сигналы, а также уменьшения их диссипации при прохождении по компонентам устройства.The invention relates to the field of non-destructive testing and can be used to study inhomogeneities in the structure of solid and liquid media. The claimed invention expands the possibility of using the laser-acoustic method for monitoring solid and liquid media by eliminating the need to provide a flat surface of the test material, increasing the accuracy and reliability of monitoring by reducing the influence of the quality of acoustic contacts and natural vibrations of device components on the recorded acoustic signals, as well as reducing their dissipation when passing through the components of the device.
