UV Proyects

Fresnel Interferometer Array

This is a France led proposal to carry out high angular resolution, high dynamical range imaging suitable to image exoplanets and resolve structures to scales of 0.01 mas in its optimal configuration. The optical design is being developed at the Toulouse University/Mid Pyrinees Observatory/IRAP. Image is formed by diffraction (instead of the common reflection or refraction) in a two ships, formation flying space telescope. One of the ships deploys the screen diffracting the radiation and another contents the optics. The proposal was submitted to ESA call for medium size missions in 2009 but was rejected because of its low TRL. The concept has been successfully tested in the optical range on the ground using the Nice telescope (2011), and in the near UV (air UV) in the lab. A prototype is under study to be installed in the International Space Station to reach high TRL in the far UV.
