Technique for Stabilizing a Spectrograph 1000x Using an Interferometer with Crossfaded Delays

David J. Erskine

Not Accessible

Your library or personal account may give you access

Abstract

By weighting signal components from at least two overlapping delays in an externally dispersed interferometer one can reduce by about 1000x the net shift in response to a wavelength drift in the disperser.
