Abstract : This year involved continuation of the development of the Mark III stellar interferometer, which is a fringe-tracking long-baseline Michelson interferometer designed primarily for wide-angle astrometry at the milli-arcsecond level. It also is useful for measuring stellar diameters and as an initial test bed for concepts relevant to aperture synthesis imaging. It is being constructed on Mount Wilson, California.
