The Michigan Infrared Beam Combiner (MIRC) combines the light from all six CHARA telescopes simultaneously. It disperses light across 8 spectral channels in the near infrared H-band (1.6 microns). It was developed by John Monnier and his optical interferometry group in the Astronomy Department at the University of Michigan. MIRC has produced the first images of a main sequence star other than the sun, measured the oblateness and gravity darkening of rapid rotators, imaged starpots on the surface of magnetically active stars, and detected faint binary companions at small separations.
