| Abstract: | A new millimeter wave CT system is set up and studied, applying the plane wave diffraction CT principle to perform non-destructive tests for dielectric materials. In order to generate the required plane wave front and comparatively narrow beam of illumination, an offset parabolic antenna in conjunction with a null bridge system has been designed and setup. Some experimental results of reconstructed images for objects under test are given under frequency of 30GHz. |
