Question:

Let Î©_sbe the solid angle subtended by the source when viewed from the center of the aperture screen. Show that

Ac Ω, Σ

represents the coherence area. This equation is useful when we don€™t know the distance to the source. Notice that the smaller the source, the larger is the coherence area.
