摘　　要：In this paper,a detailed introduction is given to the check method of the BRDF experiment bench which is built on our own. Measurement is made on the BRDF of the standard white plate made of polytetrafluoroethylene(PTFE)with reference to the existing standard white plate whose surface reflectance is known and by the method of theory approximate and relative comparison. On the basis of that,the BRDF value of the standard white plate in the wave band of 0.6328μm is given and the experiment bench is checked,the relative error of the experiment bench being within 20%.In this paper, a detailed introduction is given to the check method of the BRDF experiment bench which is built on our own.
