By adapting the principles of interferometry first developed by Michelson, we have built a simple incoherent interferometer which operates efficiently from 2 to 20 microns
The design and performance of this instrument will be discussed More than 12 stars have been at least partially resolved at one or more wavelengths and, in several cases, their sizes and shapes have been determined A number of objects in the solar system have also been studied and useful studies of extragalactic nuclei are now possible. With the development of the new Multiple Mirror Telescope both the resolution and the sensitivity of this instrument will soon be extended.
