Abstract

In January of 2002, we began routine observations using the Navy Prototype Optical Interferometer with six siderostats operating simultaneously. We present recent images obtained with this 6-beam operations mode of the NPOI. We report on the implemented system enhancements that make this possible, such as the beam combiner, fringe detection electronics, fringe tracking algorithm and the control system. We discuss the present state of the NPOI data analysis, including amplitude and phase bias corrections, cross talk considerations, and calibration issues.
