Externally Dispersed Interferometry for Precision Radial Velocimetry


Externally Dispersed Interferometry (EDI) is the series combination of a fixed-delay fieldwidened Michelson interferometer with a dispersive spectrograph. This combination boosts the spectrograph performance for both Doppler velocimetry and high resolution spectroscopy. The interferometer creates a periodic spectral comb that multiplies against the input… (More)
