Abstract: The low-coherence broadband white light source presents the problem of aging, damage. Such light source with problem used in the white light Interferometric instrument will cause incorrect data. Especially when the damage of the light source is not obvious, the wrong result will not be found easily. In this paper with the theoretical analysis and computer numerical simulation, some kinds of exceptional spectral distributions and some kinds of exceptional interferometer fringes are given. The same conclusions are achieved in the experiment. The erroneous judgment of zero-order fringe due to the damage of the light source will be avoided.
