“…Existing techniques for the nondestructive testing (NDT) of composite materials [ 6 , 7 , 8 , 9 ] are dedicated to industrial applications with low spatial resolution. Currently, the high spatial resolution needed for studying the microscopic structure of reinforced composites is provided only by techniques such as impulse acoustic microscopy [ 10 , 11 , 12 , 13 ] and X-ray computer microtomography (micro-CT) [ 14 , 15 , 16 , 17 ].…”
