WebFor an incoherent mechanism, it is defined as that "the intensity (or luminosity) of radiation from the source is less or equal to the sum of the intensities of spontaneous emission from different parts of the source" and as "due to spontaneous emission when the corresponding absorption process is unimportant" . From these definitions, we come ... WebThe spatial coherence of light with thermal origin is also normally small, because it arises from uncoordinated (incoherent) emission from a substantial area. Higher spatial coherence can be obtained by using thermal emission from a small emitter.
