项目摘要

Ultrasound imaging is an important technique utilized for medical diagnosis and damage detection in a variety of industrial applications. In most conventional ultrasound imaging systems, a pulse is emitted from an ultrasonic transducer, and transmitted or reflected ultrasound pulses are measured with a similar transducer. In this project, instead of using a conventional transducer, a laser-based system will be utilized to measure the ultrasound. This is a potentially transformative method that may have unique advantages relative to conventional methods, including reduction of measurement errors, and the ability to create full-field videos of traveling wavefronts. The project will address the fundamental challenges needed to enable laser-based ultrasonic measurements to be utilized for industrial applications and biomedical research. A strong outreach effort will use measured videos of acoustics fields to motivate secondary students to become interested in science and engineering. These videos will allow students to engage in topics such as how ultrasound imaging works, why shock waves produced by pile driving are of concern for marine life near construction sites, and how layering in the ocean is used for long-range communication by both the military and marine mammals.To detect ultrasonic waves optically, the measurement arm of a laser interferometer is directed at a stationary retroreflective surface. When an acoustic wave passes through the measurement laser beam, the wave?s density variations produce phase shifts that can be detected by the interferometer. This project anticipates a wide range of outcomes. Interferometric measurements of ultrasonic fields have often been performed using a commercial laser Doppler vibrometer. However, vibrometers are engineered to measure vibrating surfaces; they are not optimized for measuring acoustic fields. The project will investigate designs for implementing an Open Source Acoustic Interferometric Detector to enable other researchers to construct a system optimized for interferometric measurements of ultrasound fields. An important outcome will be a protocol to actively monitor and control ultrasonic standing wave formation. This will produce a doubling of the force applied by ultrasound radiation force excitation. Other outcomes will enable multiple measurements to be combined to obtain high-fidelity and depth-sensitive interferometric measurements at higher frequencies than have been obtained in previous studies. These single-point and full-field measurements will not be susceptible to some of the artifacts observed when ultrasound is measured with conventional transducers. Interferometric measurements of ultrasonic fields will be used to investigate the fluid/structure interactions that lead to Mach shock formation when a wave pulse passes through an object.
超声成像是在各种工业应用中用于医疗诊断和损伤检测的重要技术。在大多数传统的超声成像系统中,脉冲从超声换能器发射,并且发射或反射的超声脉冲用类似的换能器测量。在这个项目中,而不是使用传统的换能器,基于激光的系统将被用来测量超声波。这是一种潜在的变革性方法,相对于传统方法可能具有独特的优势,包括减少测量误差,以及创建行波波前的全场视频的能力。该项目将解决使基于激光的超声波测量能够用于工业应用和生物医学研究所需的基本挑战。一个强大的推广工作将使用测量的声场视频,以激励中学生成为科学和工程的兴趣。通过这些视频,学生们可以了解超声波成像的原理,打桩产生的冲击波为何会引起建筑工地附近海洋生物的关注,以及海洋中的分层结构如何被军事和海洋哺乳动物用于远距离通信。为了光学检测超声波,激光干涉仪的测量臂指向静止的回射表面。当声波通过测量激光束时,波?的密度变化产生可以被干涉仪检测到的相移。该项目预期会产生广泛的成果。超声场的干涉测量通常使用商用激光多普勒测振仪进行。然而,振动计被设计用于测量振动表面;它们并不适合测量声场。该项目将研究用于实施开源声学干涉测量检测器的设计,以使其他研究人员能够构建一个优化的超声场干涉测量系统。一个重要的成果将是积极监测和控制超声驻波形成的协议。这将产生由超声辐射力激励施加的力的加倍。其他成果将使多个测量相结合,以获得高保真度和深度敏感的干涉测量在更高的频率比以往的研究中获得。这些单点和全场测量将不容易受到当使用常规换能器测量超声时观察到的一些伪影的影响。超声场的干涉测量将用于研究当波脉冲穿过物体时导致马赫激波形成的流体/结构相互作用。
