摘要

我们报告了一个连续波太赫兹计算机断层扫描利用贝塞尔光束产生的轴。利用滤波后的反投影算法重建了不同距离处塑料管内部结构的二维截面图像。与传统的高斯光束相比，贝塞尔光束可以扩大景深，提高重建的保真度。

Continuous-wave Terahertz Computed Tomography Based on Bessel Beam

We report a continuous-wave terahertz computed tomography using Bessel beam generated by the axicon. Two-dimensional cross-sectional images of the internal structure of plastic pipes at different distances are reconstructed by using the filtered back projection algorithm. Compared with conventional Gaussian beam, Bessel beam can extend the depth of field and improve the fidelity of the reconstruction.
