The principle and calculation process of getting the luminance distributed matrix by single point spectral irradiances scanning method were discussed. The luminance distributed matrix could provide more detailed information. It was shown that non-uniformity characteristic in micro-scale was effected by lamps position. Then, the non-uniformity characteristic in full-scale was expressed by luminance uniformity which was calculated with 3 different definitions.
