摘要

宽带超声光谱用于定位约50 $\ μ $m或更宽的弹道冲击造成的损伤。该方法可以确定缺陷的发生深度和裂纹的长度，其精度分别不超过200 $\mu$m和不低于500 $\mu$m。金属制品厚度可达20厘米，横截面积为3至10平方米。

Internal Structure Research of 3D Printed Cellular Structures by Laser-ultrasonic Structuroscopy

Broadband ultrasonic spectroscopy is used for locating of damages due to ballistic impacts about 50 $\mu$m wide and more. The method allows the depth of occurrence of defects and the length of cracks to be determined with an accuracy of no more than 200 $\mu$m and no less than 500 $\mu$m, respectively. Metal articles may be up to 20 cm thick with a cross-sectional area of 3 to 10 m2.
