The generalized grating imaging based on the equations derived in a previous paper [ J. Opt. Soc. Am. A 25, 2244 (2008) ] is described. There the fundamental order imaging was interpreted for gratings with real diffraction coefficients. Here the equations for higher-order imaging are derived and discussed for more general gratings with complex diffraction coefficients. Based on the derived equations the contrast of the grating image is calculated for two examples. A discussion of the effect of the spectrum width of the light source is made and applied to the examples.
