Figure 1.11 shows the averaged values |γ (x)|
2 determined by the integral method
and also the values of spatial coherence function found with the help of pure holographic method (in both cases one hologram was processed, and spatial coherence
function was determined relative to the same laser end points). It is seen that though
some details in the behavior of |γ |
2 are not reflected in the integral curve, in general,
both curves (a) and (b) in the Fig. 1.11 look similarly. So, the coherence area defined
