　　在传统的采用发散照明的相位测量轮廓术中，为了准确得到被测物体的高度分布，测量前必须将参考平面坐标与相位分布之间的映射关系计算出来并以数据表的形式存储在计算机中备用。文中研究改进了投影条纹的分布，使投影到参考面上的条纹满足周期性分布，参考面上的相位分布是坐标的线性函数，无须提前将参考面坐标与相位分布的映射关系计算好并储存于计算机中，提高了测量精度，简化了实验装置。实验表明所提出方法的可行性与有效性。

In phase measuring profilometry using traditional divergence lighting, for getting the height distri?bution of measured objects accurately, the mapping relationships between the reference plane coordinates and phase distributions must be calculated and stored in computers in the form of a data table for backup before mea?surement. The distributions of improved projection fringe are researched, so the stripes projected to the reference surface meet periodicity distribution. The phase distribution on the reference surface is a linear function of the co?ordinate. So the mapping relations between the reference surface coordinate and phase distributions are not need?ed to calculate and store in the computer in advance, and the measurement accuracy is improved and experimental apparatus are simplified. Experimental results show that the method is feasible and effective.
