Abstract

Terahertz frequency range imaging has become more and more attractive for a wide range of practical applications; however, further component optimization is still required. The presented research introduces 3D-printed high-impact polystyrene (HIPS) beam-shaping components for the terahertz range. Gaussian, Bessel, and Airy beam-shaping structures are fabricated, and different combinations are employed to evaluate imaging system performance. The combination of the Gaussian element as focusing and the Bessel element as collecting is revealed to be similarly efficient and less sensitive to misalignment than the classical Gaussian-Gaussian element setup. The presented research paves the way for introducing cost-effective structured light beam-shaping elements into THz imaging systems.

摘要

太赫兹频段成像在广泛的实际应用中变得越来越有吸引力；然而，仍需要进一步优化组件。本研究介绍了用于太赫兹频段的3D打印高抗冲聚苯乙烯（HIPS）光束整形组件。制造了高斯、贝塞尔和艾里光束整形结构，并采用不同组合来评估成像系统性能。结果表明，与传统的高斯-高斯元件设置相比，将高斯元件用作聚焦元件和将贝塞尔元件用作收集元件的组合同样高效，并且对失准不太敏感。本研究为将具有成本效益的结构化光束整形元件引入太赫兹成像系统铺平了道路。
