Spectral Modification by Diffraction and Scattering

Figure 2

(a) The spectral profile of the light incident to a phase step formed by the Michelson interferometer versus 𝜆/𝜆₀ (𝜆₀=510 nm). The plots (b^′), (c^′), and (d^′) on the right are the experimental spectral profiles of the incident lights (a) diffracted from the step at points corresponding to different distances from the step edge. The plots (b), (c) and (d) on the left are the corresponding spectral profiles obtained by simulation.
