21. Another device user laser interferometry to register extremely tenuous amounts of condensation. 22. Astronomers actually do this at radio frequencies see Very Long Baseline Interferometry . 23. Although there have been many advancements in seismic interferometry challenges still remain. 24. Because of this property, it is widely used for astronomical interferometry . 25. However, this claimed interpretation of the interferometry function has been criticised. 26. Astronomers specializing in a burgeoning field of physics called optical interferometry believe so. 27. But the magic of interferometry made up for the site's shortcomings. 28. Astronomical interferometry has a rich history at Mount Wilson. 29. Very Long Baseline Interferometry ( VLBI ) . 2. 30. But the disadvantage is that even tiny errors can spoil observations using optical interferometry .
