Paper Abstract
Externally dispersed interferometry (EDI) uses a hybrid spectrometer that combines a Michelson interferometer in series
with a grating spectrometer. EDI provides a means of deriving spectral information at a resolution substantially higher
than that provided by the grating spectrograph alone. Near IR observations have been conducted using the Triplespec
spectrometer mounted on the 5m Hale telescope. Spectra have been reconstructed at a resolution of ~27000 where the
resolution of Triplespec is ~2700. Progress in the development of the EDI technique is reported herein emphasizing
studies related to the accuracy of the reconstructed spectra.
