All reflective THz telescope design with an inflatable primary antenna for Orbiting Astronomical Satellite for Investigating Stellar Systems (OASIS) mission

With an inflatable membrane, a space antenna having an order of magnitude larger photon collection area as compared to the state of the art is feasible. An integrated and comprehensive study has been performed by the scientists and engineers team at NASA Goddard, Northrup Grumman, L'Garde and University of Arizona. As a part of the study, optical design for the 19m antenna is overviewed here.
