b. Spatial coherancy & source size

b. Spatial coherancy & source size Spetial coherancy is related to the size of the source. Source size governs spatial coherancy and maller source sizes give better coherancy. we define the distance dc, the effective source size for coherent illumination to be , D c << ? / 2 ?
