Fringes from Group Delay Tracking at NPOI
The two frames below show time series of fringes. Each image represents
90 seconds of data, with each time sample spaced at 2 ms.
The upper figure shows a
single channel as a function of time. An 8-bin algorithm is used at
the Navy Prototype Optical Interferometer (NPOI)
and the 8 bins are shown as intensities along the vertical direction within
each small (horizontal) strip.
The second figure shows a superposition of three channels to simulate
a broadband fringe, each channel represents a different color (wavelength)
and the colors have been added together.
