It is well known that narrow-band thermal light can be simulated by moving a ground-glass plate in front of a laser beam (a so-called quasi-thermal source). In this Letter, we show that, when time integration of intensity occurs, the spatial correlation of integrated intensity from a quasi-thermal source does not, in general, behave as it would for a real thermal source. In particular, time integration can increase the spatial coherence area.
