The propagation mechanisms of noise imposed on the light used to illuminate complex optical systems, from the noise source to the signal readout, can be very complicated, such as gravitational wave detectors. It is very important to understand these mechanisms both qualitatively and quantitatively, in order to effectively suppress the noise contribution to the interferometer readout. In this article, a method for the systematic treatment of the noise propagation mechanisms, and a way to analyze a noise contributions in complex optical systems, is described.
