本文应用富里叶变换形状测试技术（ＦＴＰ），针对人体关节面进行了测试研究，并从实际应用角度分析了ＦＴＰ技术的误差及其改进方法，通过对标准平板和标准圆柱面的测定结果表明，精度可以达到０．０５ｍｍ以上。

An experimental research on the shape of joints surface is conducted,suing the Fourier Tranform Profilometry(FTP).The errors associated with the practical application of FTP technique are analyzed and the corresponding refinements are presented.The results of the experiments on the standard flat and cylindrical surfaces respectively show that FTP technique has an accuracy of th least 0.05mm.
