In this paper, we study of the impact of low-frequency noise on terahertz-computed tomography (THz-CT). Two acquisition methods are compared in order to analyze how the low frequency noise is projected into the 3D image after reconstruction.

Low-frequency noise effect on terahertzTerahertz radiation is electromagnetic energy commonly associated with frequencies around 0.1 to 10 THz, between microwaves and infrared, where many materials reveal distinctive propagation, absorption, and imaging behavior.
