This dissertation describes work performed at the Palomar Testbed Interferometer (PTI) during 1998-2002. Using PTI, we developed a method to measure stellar ang

The imaging process in stellar interferometers is explained starting from first principles on wave propagation and diffraction. Wave propagation through turbule
