Question: A circularly symmetric light source has an intensity distribution I () = I 0 exp[ 2 /(2 0 2 )], where is the angular

A circularly symmetric light source has an intensity distribution I (α) = I₀ exp[−α²/(2α₀²)], where α is the angular radius measured from the optic axis. Compute the degree of spatial coherence. What is the lateral coherence length? What happens to the degree of spatial coherence and the interference fringe pattern if the source is displaced from the optic axis?
