Condition for the invariance of the spectral degree of coherence of a completely coherent light wave on weak scattering.
The spectral coherence of a light wave on scattering is closely related with the properties of the scattering medium. Within the accuracy of the first-order Born approximation, we present the condition for the invariance of the spectral degree of the coherence of a spatially coherent scalar plane light wave on scattering, and we discuss several typical examples on weak scattering.
