Delft testbed interferometer

DTI is an optical testbed to demonstrate homothetic mapping, a special method for optical aperture synthesis. It has been assembled and aligned, and characterised. As a result it can be stated that all requirements posed on the system have been met. White light fringes on three ‘stars’ have been obtained proving that homothetic mapping is possible within the DTI system, a worlds first for TNO TPD. DTI is a research topic of the Knowledge-Centre for Aperture Synthesis (KAS), and is available for researchers in the field of aperture synthesis and homothetic mapping.
