Paper Abstract

Different effects induce spectral changes; for example, correlation of the fluctuations in source, propagation of light, random changes of optical properties of medium, diffraction and scattering from objects and rough interfaces. In this report we review the spectral changes that occur as result of light diffraction from phase steps and particularly we emphasize on the effect of phase singularities on spectral changes. We also review the redshift and blueshift in the spectra of the lights coherently and diffusely scattered from rough interfaces. In addition, we study the effect of roughness and incident angle on spectral profile of light scattered in reflection and transmission modes.
