The project is concerned with research in optoacoustics, focuses on both fundamental and novel applications, and emphasizes experimental work. Three topics are covered in this activity and include optics and optoelectronics applications in acoustics, development of fiber optics devices to measure normal and tangential micro-vibrations on surfaces, and outdoor sound propagation. The first topic involves the applications of acousto-optic light modulation with Bragg cells to the laser generation of ultrasound in materials. This non-contact method of sound generation is attractive where the environment is either too hot or radioactive. The second research topic's outcome is expected to provide information on the mechanisms controlling sound radiation from fluid/structure interactions. The third topic is concerned with the modeling of sound diffraction from irregular topography. It may find applications in environmental acoustics and noise near airports.

该项目涉及光声学研究，重点关注基础和新颖应用，并强调实验工作。 本活动涵盖三个主题，包括光学和光电子学在声学中的应用、开发用于测量表面法向和切向微振动的光纤设备以及室外声音传播。 第一个主题涉及布拉格细胞声光光调制在材料中激光产生超声波中的应用。 在环境太热或有放射性的情况下，这种非接触式发声方法很有吸引力。 第二个研究课题的成果预计将提供有关控制流体/结构相互作用的声辐射的机制的信息。 第三个主题涉及不规则地形的声音衍射建模。 它可能会在机场附近的环境声学和噪声领域得到应用。
