5First-Order Coherence of Light
The concept of first-order coherence was introduced in classical theory of light to quantify the interference between temporally delayed or spatially separated electromagnetic waves. The superposed radiations are defined as first-order coherent if the interference fringes exhibit 100% modulation, or first-order incoherent if no interference fringes are observable. The radiation fields are considered as partial coherent if the modulation is less than 100%, however, greater than zero. The higher the degree of first-order coherence, the higher interference visibility we could observe. Although it is named “coherence” and is an intrinsic property of the radiation itself, either temporal or spatial, the concept is ...
