Abstract

In this talk I introduce the principles of radio interferometry, using the new low-frequency array LOFAR as an example. One of the planned projects for LOFAR consists of finding new gravitational lens systems at radio wavelengths. I explain the motivation for this project and discuss fundamental relations between gravitational lenses and interferometry. In addition, I also mention quantum-mechanical and relativistic subtleties of radio interferometry.
