摘　　要：本文提出了用白光获得板面曲率的显色云纹方法。理论和实验分析说明，曲率和斜率的显色云纹可用于其级数的自动识别。本方法具有不必经过计算，实时确定条纹级数的优点，对于曲率和斜率测量方法和系统的完善具有实际意义。A colour clouding method for measuring surface curvature using white light is given。It is shown by the theory and experiments that the colour clouding of slope and curvature can be used to in-dentify its order automatically. Without calculation,the method can determine the order of the fringes in real time. It has practical significance when it is used to measure the curvature and slope and to im-prove the system.
