In this chapter, a spatial–spectral correspondence relationship is introduced, which can be applied to monochromatic light diffraction or propagation. The conditions that make this relationship valid are discussed and its mathematical forms in the near and far field are given. Many interesting results based on this approach are presented, including the Fresnel zone spectra and Talbot spectra. Other effects or applications such as the spectral shift amplification and lattice spectroscopy are also analyzed. Another related phenomenon called the spectral switch is also discussed. This is the discontinuous jump for the diffracted spectral maximum shift when continuously varying the detected position or system parameters. Three different mechanisms generating the spectral switch and the way to use them for digital data transmission are introduced. It is believed that this correspondence relationship will play an influential role in transforming monochromatic results in the spatial domain into chromatic ones in the spectral domain.
