| Abstract: | Terahertz pulsed imaging has been used to perform computed tomography of three-dimensional objects inducing high refraction losses. We were able to obtain cross-sectional images of the targets by using a computed tomographic analysis of the terahertz signal based on a multi-peak averaging procedure. Some examples are presented of objects with complex shape such as a Teflon cylinder and a dried chicken bone. |
