CHANGES IN THE SPECTRUM OF LIGHT ARISING ON PROPAGATION THROUGH A LINEAR TIME-INVARIANT SYSTEM

[摘要] The spectrum of light, in general, changes when the light interacts with a dispersive medium or when it is diffracted. It may also change on propagation, even in free space, because of the coherence properties of the source. The difference and some similarities between these processes of spectral modification are analyzed.
