论文摘要
ShadowMoiré技术是针对光波制定的，用于图像3D对象，以确定其表面拓扑。在本文中，我们在实验上证明，也可以使用超声来创建Moiré图像。使用Moiré技术将增强超声应用，例如医学成像和材料表征。在我们的实验中，我们使用了由铝制的光栅面膜，铝制范围的超声源和声学探测器的超声源来创建和捕获用于光栅的塔尔伯特图像。使用和声音相机捕获塔尔伯特图像。捕获的图像是从λ= 0.43 mm的超声波产生的。图像的边缘证明了它们是影子莫雷条纹。
Shadow moiré techniques are developed for optical waves to image 3D objects to determine their surface topology. In this paper we prove experimentally that also ultrasound can be used to create moiré images. Using moiré techniques will enhance ultrasound applications, such as medical imaging and material characterization. In our experiment, we used a grating mask made of aluminum, an ultrasound source in the megahertz range, and an acousto-optic detector to create and capture Talbot images for the grating. Talbot images are captured using and acousto-optic camera. The captured image was created from ultrasound waves with λ=0.43 mm. The fringes of the images proved that they are shadow moiré fringes.
