基于最小不确定度的统计准则，已经发现存在源和仪器参数的最佳组合，这导致在测量和确定线轮廓位置或温度中最有效地使用法布里-珀罗光谱仪。给出的结果，以优化光谱仪的设计和/或定量地推断从测量的测定的不确定度。目前的结果之间的比较，光度分辨率产品的方法，和通常的方法来确定线的位置显示本定量方法给出最有效的光谱仪和最好的不确定性估计。一个有用的研究结果表明，低反射精细标准具提供了最佳的光谱仪。由该结果导出的平板表面质量的隐含松弛和标准具调整精度，不仅简化了操作，而且降低了仪器成本。
Based on the statistical criterion of least uncertainty, it has been found that there exists an optimum combination of source and instrumental parameters, which lead to the most efficient use of a Fabry-Perot spectrometer in the measurement and determination of either line profile position or temperature. Results are given in order to optimize the design of a spectrometer and/or quantitatively deduce the uncertainties of determination from measurements. Comparisons between the present results, the luminosity-resolution product method, and the usual method to determine line positions show the present quantitative method to give the most efficient spectrometer and the best estimates of uncertainty. A useful result of this investigation shows that a low reflective finesse etalon provides the optimum spectrometer. The implicit relaxation of the surface quality of the flats and precision of etalon adjustment deduced from this result lead not only to simplified operation but to lower instrumental costs as well.
