We have generalized the notion of Franhoufer diffraction of temporal coherent light from a single slit to the case of arbitrary n slits. A general numerical method has been developed for the simulation of the diffraction pattern of multi-slits which is also used to study the effects of coherence length on the diffraction pattern. The diffraction pattern is investigated for different values of recently introduced parameter, decoherence parameter. It is shown that for multi-slits, the temporal decoherence effects appear for decoherence parameter more or equal to one. The results of our study reproduce the previous studies for perfect temporal case, when coherence length tends to infinity.
