WebStructure has several other important uses: First, you can structure sentences for emphasis, drawing attention to the most important part of the sentence. Second, you can structure your sentences and paragraphs to flow — that’s what cohesion and coherence are all about. Cohesion is the degree to which sentences “glue.”. WebNov 21, 2024 · The auto-correlation function, which is the same as coherence function, is the Fourier Transform of the Power Spectral Density of the source. For short coherence, a wide band source, I.e white light source is needed. The greater the bandwidth the shorter coherence length, but coherence function is maximum at zero time shift.
