A continuous-wave terahertz 3-D computed tomography using a pyroelectric array detector
摘要
Abstract
Terahertz computed tomography makes use of the penetrability of terahertz radiation and obtains three-dimensional(3-D) object projection data.In this paper,continuous-wave terahertz computed tomography using a pyroelectric array detector is presented.Compared with scanning terahertz computed tomography,a pyroelectric array detector can obtain a large quantity of projection data in a short time.To obtain a high precision two-dimensional(2-D) projection data,the two-dimensional projection data is propagated by angular spectrum algorithm;then the diffraction effects are suppressed on external sample.Two-dimensional cross-sectional images and three-dimensional images of the internal structure of the object are obtained by the filtered back projection algorithm.Further,the feasibility of terahertz computed tomography is explored in non-destructive testing and security testing.关键词
