摘　　要：介绍了一种应用于生产现场能决这判定车灯反光镜在各工艺阶段表面粗糙程度和面形误差的方法。详述了测量原理．测量装置的构成，实验以及实验数据。In this article, we describe a method to decide quickly the reflection surfacequality of the reflector of the automobile light in the procession of production. Using thismethod, we can know the relative roughness and the shape error of its surface. Meanwhile,we describe the principle of the measurement, the construction of the device, the experi-ments and its results.
