The Aragoscope: Ultra-High Resolution Optics at Low Cost starts from 1 hour into the video.
The goal is to create space telescopes with hundreds of meters of diameter.
The Aragoscope diffracts light into collection areas. A fraction of the light is collected. A hundred meter aragoscope with many 3 millimeter to one centimeter of width the diffracting rings would collect the light of a one meter telescope. The diffracting rings are a few microns across.
A conventional space telescope is pointed at an opaque disk along an axis to a distant target. The disk boosts the resolution of the system with no loss of collecting area. It can be used to achieve the diffraction limit based on the size of the low cost disk, rather than the high cost telescope mirror. One can envision affordable telescopes that could provide 7 centimeter resolution of the ground from geosynchronous orbit or images of the sky with one thousand times the resolution of the Hubble Space Telescope.
