In an observing campaign between 1997-1999, the Infrared Optical Telescope Array (IOTA) obtained interferometric measurements in the near-infrared J, H and K bands for a sample of 28 long period variable (Mira) stars. This spectral coverage is important in order to constrain the atmospheric physics in these stars. Our preliminary results, in the form of stellar diameter estimates at each band are presented and discussed.
