Spectral Modification by Diffraction and Scattering

[摘要] Different effects induce spectral changes, for example, correlation of sourcefluctuations, propagation of light, random changes in optical properties ofa medium, diffraction and scattering from objects, and rough interfaces. We review the spectral changes that occur as a result of lightdiffraction from phase steps, and particularly we discuss the spectral changesin the neighborhood of phase singularities. We also review the redshift andblueshift in the spectra of the lights coherently and diffusely scattered fromrough interfaces. In addition, we study the effects of roughness and incidentangle on the spectral profiles of scattered lights in reflection and transmissionmodes.
