Fizeau interferometry Sample Clauses

Fizeau interferometry. Xxxxxx interferometry has been studied widely at other wavelengths and is still considered as a potential candidate for a future FIR interferometer. The possibility of multiple telescopes collecting portion of the same wavefront and combining these at the detector focal plane has a number of advantages (large multi-segment adaptive optics telescopes are in a way the limit for minimal mirror separation), although this arrangement competes with the preferred “nulling interferometry” suggested for both the Darwin space interferometer (ESA cornerstone mission proposed and then abandoned in the last decade) as well as the NASA Terrestrial Planet Finder (cancelled in June 2011) interferometer concepts. We have however in this activity, recognized that Fizeau interferometry presents a useful and practical opportunity to demonstrate the capabilities of interferometry in space. As such we linked the activity of Task 3.2 with the cube-sat technology validation activity and took forward the idea of developing the first small satellite concept that would perform interferometry in space, as well as working together with XXX on the development of the algorithms for image reconstruction of the small hyper-telescope demonstrator.
