At this very moment a few companies in the world are in the final testing phase for the deployment of passive imaging systems for indoor security applications in the W-band (75-115 GHz). In this lecture we will address the actual problems of these passive indoor imaging systems and will explain the need for active imaging systems. The transition to active illumination systems is not straightforward due to inherent optical aberrations and noise sources such as speckle, ringing and glint. We will highlight the importance of stochastically independent multi-parameter illumination schemes to achieve high quality images. We will briefly discuss the different tracks of our development work including: novel photonically controlled intelligent flash lamp arrays, frequency selective surfaces. Besides the development work for indoor security applications, we will also take a look to the research activities in the area of scanning near-field mm-wave and THz microscopes. These microscopes are an essential tool to drastically improve the spatial resolution for the investigation of all kind of resonances in electronic, photonic and bio(techno)logical materials.
