Singular optics recognized as an important branch of modern optics has been recently developed rapidly, which has been extended from primarily dealing with fully coherent, polychromatic wavefields (called coherent singular optics) to treating partially coherent, quasi-monochromatic wavefields (called correlation singular optics), and fully coherent, polychromatic wavefields.

The phenomenon of scattering-induced spectral switches of polychromatic Gaussian beams in the far zone belongs to the effect in singular optics.
