Implementation: 1 January 1979 – duration: 27 min – Antoine Labeyrie – French
How, thanks to interferometry, it is possible to know the diameter of stars, their movements. How later, thanks Space Interferometry, we can measure the diameter of the planets. Limits of resolution of large telescopes. Use of interference as a means of measurement. Speckle interferometry. Interferometry two telescopes – several telescopes – synthetic aperture. Views real – animations.
