摘　　要：对用Talbot效应及云纹干涉法测试镜面反射体曲率和斜率的灵敏度进行了分析,同时给出了由于光栅稀密对测试的影响和相应的解释。这对从事这项工作或工程上利用此技术测试物体曲率和斜率提供了一个可行的方案。In the paper, the sensitivity of measuring the mirror reflecting body curvature and slope are analysed. The measurement is carried oat with Talbot effect and moire interferometry, in the meanwhile the effects of compactedness of grate on the measurement is also analysed and the relative explanation is given. It provides a feasible scheme for the engineers being engaged in relative work to measure the curvature and slope of substances by use of this technology.
