View source for Engineering:Mechanically induced modulation

'''Mechanically induced modulation''' is an optical signal [[Engineering:Modulation|modulation]] induced by mechanical means. 

An example of deleterious mechanically induced modulation is speckle [[Physics:Noise|noise]] created in a multimode fiber by an imperfect [[Engineering:Fusion splicing|splice]] or imperfectly mated connectors. Mechanical disturbance of the fiber ahead of the joint will introduce changes in the modal structure, resulting in variations of [[Biology:Joint|joint]] loss. This is a subset of many mechanisms that can lead to modal noise in an optical system.
