| 摘 要： | 通过对光学测量中常见的叉线对准以及焦距、曲率半径测量进行大样本数据采集和分析处理,利用实验方法得到常见光学测量数据的分布,并选择Beta分布统示表示多种分布,简化了光学测量中的分布研究.研究结果可以作为贝叶斯统计中的数据先验分布,用于对一般测量进行贝叶斯方法的不确定度评定. |
| 关 键 词： | Beta分布 统示分布 光学测量 对准 焦距 曲率半径 |

| Abstract: | Large sample data of alignment, focus measurement and radius of curvature measurement are acquired and analyzed. They are common optical measurement and their distributions are obtained from the large sample data. Beta distribution is used as a unified distribution to simplify the research of optical measurement distribution. The research result could be used as prior distribution in Bayes approach to evaluate uncertainty in optical measurement with practical prospect. |
| Keywords: | Beta distribution Unified distribution Optical measurement Alignment Focus Radius of curvature |
