Abstract
Integrating sphere has been widely used in the photoelectric integrating color measurement. Ordinarily, the measurement caliber of integrating sphere is smaller than the diameter of incidence beam, and some of the incidence beam irradiate on the inner surface of integrating sphere directly. It introduces error into the color measurement. The paper establishes the mathematics model of the error introduced by integrating sphere in color measurement, and has found the way to revise the error. The result indicates that this method can revise the error which is carried by the mismatch between the measurement caliber of integrating sphere and the diameter of incidence beam effectively.
