An imaging system in the sub millimeter area

The millimeter wave frequency range was pushed through test systems for production lines in the last years. Non destructive test systems for quality control need more powerful sensors to detect non-metallic pollutions inside packages. The millimeter wave frequency range up to the lower terahertz frequencies (T-ray imaging) offers the opportunity to look through many packages. Alternative applications are the detection of non metallic and/or under cloth wearied weapons. Other fields of interest for this frequency range are medical applications, especially the detection of skin cancer.
