Spatial coherence
Spatial coherence is a concept of wave disturbance describing the correlation between periodic transmitted energy (wave signals) from one point to another,it can also be said that it is a mutual interdependence or connection of variable wave quantities,the coherence is presented as a function of distance; the correlation against an absolute distance between points in question.
