Paper Abstract

We discuss NPOI data, their reduction and limitations, in the areas of delay power spectra, diameter measurements of variable stars, imaging of spectroscopic binaries, and astrometry. The Navy Prototype Optical Interferometer is a three baseline (to be expanded to 15) broad-band array of 50 cm siderostats with vacuum delay lines. With NPOI, the limb- darkening of stars has been detected, images resolving spectroscopic binaries down to a few milliarcseconds have been made, and astrometric capabilities explored. Lessons learned and current efforts for improving the quality of the data are presented.
