Infrared Spatial Interferometer
Mentors: Sean Lockwood, Walt Fitelson (UC Berkeley)

The Infrared Space Interferometer Array (ISI) is a high resolution interferometer built by the Space Sciences Laboratory at the University of California at Berkeley, California and is used for studying the properties of stars and immediate stellar environments in the mid-infrared portion of the spectrum. The ISI is located at the Mt. Wilson Observatory.

The ISI consists of three specially designed Pfund-type movable telescopes, each 1.65m in aperture. By placing our three telescopes at varying distances apart from each other (ranging from 4m to 70m) and combining the starlight received from each one, we can obtain the same resolving power as a telescope as large as that separation in a perfect atmosphere. This allows us to spatially resolve stars, which is otherwise impossible (for most stars) from the ground.
