|
| 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.
