On the development of a quasi-optical system for short and long range standoff imagers

The European Defense Agency project TIPPSI aims to produce a phenomenology study to evaluate the performance of standoff imagers for security applications at submillimeter frequencies. In this context, a modular optical architecture is being developed. It is composed by a compact Dragonian system to image at short ranges coupled to a confocal system that operates at a larger focusing distance. The performance of the two solutions is described in this contribution.
