摘要

本文研究了一种适合于太赫兹范围内应用的数字全息技术，该技术可以对熔融沉积造型印刷产生的物体进行无损探伤。基于准光学透镜传输线的200 GHz全息图像记录系统。得到了相衬物的全息图像，其形式为两条导电丙烯腈-丁二烯-苯乙烯（ABS）带，以厚度和Y坐标分开。这些条带位于另一ABS介电材料内部。角谱法用于确定样品中人工不均匀性的位置，精度为3 mm。

Terahertz nondestructive evaluation of objects produced by additive manufacturing

The paper deals with digital holography that provides non-destructive flaw detection in objects produced by fused deposition modeling printing and suitable for application in the terahertz range. The 200 GHz holographic image recording system is based on the quasi-optical lens transmission line. Holographic images are obtained for the phase-contrast object in the form of two ribbons of conducting acrylonitrile butadiene styrene (ABS) separated in thickness and Y coordinate. These bands locate inside another ABS dielectric material. The angular spectrum method is used to determine the position of artificial inhomogeneities in the sample with a 3 mm accuracy.
