We show a design for a MIMO array whose high number of elements can accelerate the measurement process and enables inline capable 3D imaging systems. The MIMO array achieves a lateral resolution of 1mm and provides for the first time a polarization selective arrangement to better detect defects as deviations in the periodic structures of composite materials. Furthermore, the design of the high frequency PCBs for the installation of the SiGe receivers is shown as a first step on the way to a 3D imaging system.enOptical fiber polarizationMass productionThree-dimensional displaysQuality assuranceImagingReceiversstereo image processingDDC::500 Naturwissenschaften und Mathematikconference paper
