Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times. Temporal coherence tells us how monochromatic a source is. In other words, it characterizes how well a wave can interfere with itself at a different time. The delay over which the phase or amplitude wanders by a significant amount (and hence the correlatio… WebNov 10, 2024 · The coherent part of the FLASH light generates the horizontal diffraction image with a few pronounced intensity maxima; the incoherent part generates the speckle pattern above and below the coherent image.
