An Introduction to Radio Interferometry (Legacy OVRO Video)

A brief and entertaining introduction to radio interferometry by Dr. Dale Gary. The video was produced in 1991 to explain how the Owens Valley Radio Observatory solar array worked. The explanation of interferometry remains timeless and can easily be applied to modern interferometers such as ALMA and the Jansky Very Large Array. A must-watch for novices and experts!

For understanging radio interferometry visualing is very helpfull.
I hope Dr. Dale Gray. is live . Thanks for sharing .

That is not Dale Gray, but the excellent Dale Gary and he is still the best in the business at doing radio interferometry of the sun.

Many thanks, Gregg, for catching that. I'll fix that right away.

Is Dale Gary the grandfather of 3 Blue 1 Brown? This video was super helpful.

[@almaprimer920]

I'm afraid I have no idea what (or who) "3 Blue 1 Brown" is. It's a delightful and insightful video that we decided could not be improved upon, so we asked for (and received) permission to include it in this series.

@@AdrianBoyko Thanks! I'll have to check that out. Always interested in new visualization ideas.
