Sparrow limit of spectral resolution in the reflection echelon and the fabry-perot interferometer having surface imperfections.
The limit of spectral resolution as defined by Sparrow has been calculated for the reflection echelon and Fabry-Perot interferometer having a different type of polishing imperfections on the surface of the plates.For the sake of comparison the Rayleigh limit of resolution has also been calculated and compared with the Sparrow limit.
