The phase space representation in the resolution of two spectral lines: the grating spectrometer case

The aim of this work is to find a resolution value for grating spectrometers when two spectral lines are analyzed. The phase space representation is used to find this value when the following proposal is employed: If the Wigner distribution function is positive along the space frequency axis (at the origin of the space axis) then the two spectral can not be resolved; otherwise, the spectrometer resolve them.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.
