Frequency modulated terahertz imaging systems have shown a great potential for volume inspections in the industrial process and quality control. However, many system concepts lack the capability to encompass a large field of view with fast data acquisition speed, while providing significant depth information. Based on our recently outlined system design of a terahertz imaging solution for the industrial process control, we report on the realization of a stepped-frequency modulated sparse array with 12 emitters and 12 heterodyne receivers operating in the frequency range from 75 GHz to 110 GHz. The system is ready to perform imaging tasks and will be in a final step combined with a band-conveyor for fast terahertz image acquisition.
