In the paper, it is realized that the optical homogeneity of optical glass is tested layer by layer according to the interference principle of the dual surface of the matched liquid, and assisted with computer handling. The characteristic of the method is that the horizontal plane used as standard dual planes reflecting light for producing interference patterns of equal thickness, and thus it may be used for testing the optical homogeneity of optical glass when it is disappeared in the matched liquid. The result that the optical homogeneity of optical glass tested may be realized with computer. Such results have given interference pattern of optical homogeneity of any layer, in the optical glass, the biggest inhomogeneity value in this layer and the change figure on the value of any layer. The magnitude degree of testing precision is better than 10^-4.
