Resolution Specification

Definition of resolution In all cases the resolution is defined as l/Dl , where Dl is the FWHM of an emission line measured in pixels multiplied by the dispersion determined during wavelength calibration.

Why only take 2 interferograms? Why not take 2* N ?

Why only take 2 interferograms? Why not take 2* N ?. The birth of the TAURUS concept. Note: A single interferogram only contains (1/ N ) th of in spatial information Scanning the FP across a full FSR is a natural way to: Recover ALL of the spatial information
