Method for determining multi-material object characteristics, multi-material detection system and multi-material object characterization method

摘要

METHOD FOR DETERMINING CHARACTERISTICS OF A MULTI-MATERIAL OBJECT, MULTI-MATERIAL DETECTION SYSTEM AND METHOD OF DETERMINING A MULTI-MATERIAL OBJECT. It is a method (101) for determining the characteristics of a multi-material object. The method includes determining (102) an electrical element matrix representing the multi-material object. The electrical element matrix is premultiplied (104) by a first mathematical transformation matrix to obtain a first transformed electrical element matrix. The first transformed electrical element matrix is post-multiplied (106) with a second mathematical transformation matrix to obtain a second transformed electrical element matrix. The method further includes determining (108) the characteristics of the multi-material object based on the second matrix of transformed electrical element.
