Outline of talk 1.

Interferometer definition, a device that separates a beam of light into two ray beams, usually by means of reflection, and that brings the rays together to produce interference, used to measure wavelength, index of refraction, and astronomical distances. The powerful system provides astronomers with extremely detailed images of distant astronomical objects. Some practical details. 12C: Radio Observations (Ed.
