Practical coherent integration with the NPOI
Practical coherent integration with the NPOI
In this paper we will discuss the current status of coherent integration with the Navy Prototype Optical Interferometer (NPOI).<sup>1</sup> Coherent integration relies on being able to phase reference interferometric measurements, which in turn relies on making measurements at multiple wavelengths.We first discuss the generalized group-delay approach, then the meaning of …
