A system and method are provided for utilizing section contribution characteristic data to achieve accurate measurements by compensating for unwanted phosphor output variations that occur at specific sections of phosphor on a rotating high intensity phosphor point source element. Phosphor grain size, density, blend homogeneity, or illumination gap variations may cause the unwanted variations. Based on the section contribution characteristics, excitation energy compensation may provide a stable output illumination spectrum or computational compensation may correct measurements for effects arising from predictable output illumination spectrum variations. The section contribution characteristic data may comprise section wavelength intensity profile data and/or section efficiency data, in various embodiments. In some embodiments, the sections may be on the order of the size of the phosphor grains and may be characterized and compensated. The sections may include phosphor blends, or distinct phosphor types, in various embodiments.
