摘要：
In this paper, we propose a high-resolution terahertz coded-aperture imaging method with fast beam scanning for near-field three-dimensional targets. This method utilizes a coded aperture to modulate incident terahertz waves randomly and drive the terahertz beam to scan the entire imaging space step by step. Theoretical analyses based on physical optics are performed, and simulation experiments are implemented to demonstrate the feasibility of the proposed method. (C) 2019 Optical Society of America
