WebJan 9, 2024 · Coherence is an important attribute of light that makes many modern inventions possible. Devices such as lasers and hologram projectors rely on coherent light. Coherent light is also used for... In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions. Spatial coherence describes the ability for two points in space, x1 and x2, in the extent of a wave to interfere, when averaged over time. More precisely, the spatial coherence is the cross-correlation between two points in a wave for all times. If a wave has only 1 value of amplitude over an infinite length, it is perfectly spatially coherent. The range of separation betwe…
